Error 1327 – Invalid Drive when Installing HP Software

by Raphael Nikolai on January 5, 2009 and Revised on May 17, 2012

in TroubleShooting

This is a very complicated problem that may happen when installing your Hp software. This may happen when you installed the software previously on an external hard drive that has already been removed. The registry keys that point to the installation address may still be present that is why during installation it tries to find the non-existent drive. This would then give you and Invalid Drive error message when Installing HP Software.

Solution to Error 1327:

All you need to do is make a virtual drive with the letter matching the invalid drive’s.

  • Go to command prompt. Click on Run and type CMD and press ok.
  • In the command prompt type the command:

Syntax:

Subst (invalid drive letter): (existing drive letter):

 

Example:  Subst I: C:

UPDATE Febuary 6, 2009:

I would like to thank Zalia for inspiring me to seek and destroy the root cause of this problem. The solution above is still effective however it does not fully remove the root cause of the problem which are registry keys pointing to an invalid drive. Before I continue I would like to inform everybody that the next steps involves editing registry keys and if not done properly it may affect your systems stability and performance. Advanced knowledge is needed.

The Ultimate Fix: (i will not elaborate more on simple steps as I am expecting only advanced users to tackle this step.)

You need to go to “REGEDIT” by typing “REGEDIT” on the RUN dialog box and inspect the following keys on your registry. Pictures are provided for each area on your registry as an example, to show you some views on a normal registry entry for a certain local drive C.  If it does not point to the correct drive you may right click and modify it to the correct drive letter.

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders

HKEY_CURRENT_USERSOFTWAREMicrosoftWindowsCurrentVersionExplorerShell Folders

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShell Folders

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerUser Shell Folders

Make sure that directory paths on the right side is on a correct/existing drive. If it is using an invalid drive right click and modify the directory path by changing the drive letter to a correct one.

As you may see on the comments below. This article has proven itself to have a high resolution rate and is definitely worth trying. For the record, this solution also works with other software installation problems as well for the following:

Napoleon Total War (It was a Steam Program Issue) , Adobe, Gigaware, Camtasia Studio, Microsoft Activesync, Turbo Tax, Lexmark, and more!

    fixed! thanks you…!!!

    It didn’t work for me, and when I tried to rerun the command it verified that the drive was already subst.

    if you could share more detailed info about your issue in here, I would love to take a challenge…

      HI NIkolai,
      very stupidly halfway though upgrading my laptop from vista to windows 7 i turned off my cpu. I lost tons of files all in “my documents” when i try to access it, it has said invalid drive E: I tried both of your fixes, first the substitute, then using the regedit and found a few instances(one under Personal) to change from E to C. I was very excited thinking that maybe I’ll get my pc back, because ever since when I go to uninstall a program or install new programs I get this invalid error. I’ve just got back into the pc and tried to uninstall Nero which has never worked before because of this invalid error code and it won’t let me delete it because of error code 2203. I’m still trying to access the old “my documents” but it says permission not allowed and when I try to change permission it won’t let me. Any ideas?

    Yeah! after much frustration and time looking for an answer, I found it here! thanks! so easy when you know how!

  • Jarod

    Worked for me with invalid drive letter G. Thanks so much -J

  • Jarod

    I had problems installing any software with an Invalid Drive G:. As you described, I believe this stemmed from an external hard drive I’d removed or uplugged (even though the LaCie didn’t use a drive named G:, the registry keys must have pointed to it).

    Whatever was wrong this fixed. Thanks so much.

    wow. i ended up being here because i had a problem with my computer’s internet connection (probably LAN card issue), which forced me to hook up printer to my laptop — when i tried to install the printer, i couldn’t, because of the error message. this REALLY helped. i wish i could come and kiss you and give you a BIG hug!!!!

    I love you! I just love you! I’ve been working on this problem since version 8 of iTunes (maybe six months or longer) and when I finally remembered to put spaces into the string above, hey presto! iTunes 8 went straight over 7, (which I couldn’t uninstall due to the same Invalid Drive error…blech!) I’m off and running and YOU ARE A LEGEND!! -Jane from Oz

    It worked for me…Thank You!!! At first I wasn’t sure you needed to include spaces when writing the line, but I got it on my second attempt! subst(space)G:(space)C: then hit enter… I’m pretty sure that’s how it went!
    Thanks again.

    I had the same problem and have tried your solution. It works, thanks to you, but now another problem arises.

    The invalid drive F: is actually my external hard drive when it was plugged in. So now everytime I click on the F: drive, I will be pointed out to C: drive.

    I know that I can change the drive letter from F to other letters, but is there any other solution to this?

    Thank you- zalia

  • Nikolai

    @ zalia

    - This solution aims an easy fix that does not compromise your systems stability.

    However, there is another solution to this which involves advanced steps in editing your registry entries.

    you need to go to “REGEDIT” and inspect the following keys on your registry.

    *
    HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders

    *
    HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion

    *
    HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShell Folders

    *
    HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerUser Shell Folders

    and make sure that directory paths on the right side is on a correct/existing drive. If it is using an invalid drive right click and modify the directory path by changing the drive letter to a correct one.

    I found this on another forum and it worked for me after I got one with Invalid Drive: K:. I uninstalled my HP Printer and a lot of other stuff that came with it, and ever since then get that code. So I found this.

    “the way to fix it is you just plug in any kind of drive into usb port on your computer. For example, I plug my USB flash drive then computer will show the new drive that assigned for the usb dive that you just plug in, it will work.”

    It doesn’t show up as “Drive K”, but either way, I was able to install an update that I wasn’t able to before. Hope this helps.

    I had problems uninstalling Microsoft Office 2007 and I was getting the Error 1327.invalid Drive Y:

    I followed the fix instructions as given on this website and edited the registry, I found the following was the problem:

    HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders

    The value for Favourites was set to Y: So I simply changed the value to be C: and retried uninstalling Microsoft Office 2007 software and it was successful. Thanks a million!!! Gareth

    @ Gabriel, In order for me to provide appropriate solution you need elaborate more on your issue and I will do my best to help you… If the solution above did not work for you , you probably have a different issue at hand..

  • Zonny

    Gabriel,

    My problem was similar to others, but on a used Gateway. The previous user had a network engineer perform maintenance and installation of programs.

    When I tried to uninstall several programs (such as an old version of Adobe Reader and Microsoft Antispyware), I received the Error 1327: Invalid Drive E: message. (No E drive or HP software on this PC)

    I also could not simply install several common programs.

    My take on the problem was the network engineer used his skills to install and backup the owner’s programs and documents to another drive, which became the default for install/removal.

    I spent several hours trying to resolve until I came across this enlightening website. The problem extends well beyond HP. Thanks. Zonny

    Hi there,

    I’ve tried all of the above to no avail. I keep trying to install Itunes but each time it stops me and says “invalid G drive you need Quicktime” etc. I tried to substitute the letter C in place of G on the task command thing but it said invalid parameters. Please help me I am absolutely at my wits end here and now my iPhone has shut off until the program’s fixed. thanks so much

    • Nikolai

      Can you tell me what happened after doing each step above. For example, what happened after you input the subst command? Were you able to go to your registry? make sure you have thoroughly checked on it.

      The solutions above have a high success rate. I highly recommend every one make sure that it is done properly so we can then proceed to other troubleshooting alternatives.

  • Stephen

    Thanks! This fixed the problem that has been going on for a long time. My system was looking for non-existent G: drive every time I tried to install/uninstall most programs and I’d been popping in two USB sticks to get a G: drive present. In my case the registry entries pointed to directories obviously set up by Sandisk U3 software – and now I remember a time when U3 hung and I had to power down the computer.

    You may want to add to the main entry advice on BACKING UP THE REGISTRY before starting on any changes to the Registry. On XP:

    Click Start / Run and enter:%SystemRoot%system32restorerstrui.exe

    and obviously choose Backup.

    Thanks again!

  • Gregor

    I seem to have a trickier problem. I get the “Error 1327. Invalid drive I:” from InstallShield when trying to install a driver. However I: does exist and is accessible.

    It is a mapped network drive, that I cannot unmap, because I have redirected my “Documents” folder onto it, which has been working smoothly for a long time now. I also use offline folders to keep this folder accessible when offline. So here I am stuck, unable to apply the above fix, because that would mean a major change to my system.

    Any comments will be appreciated.

    • Nikolai

      I agree with you gregor… What are you trying to install by the way?

  • Jay

    I cannot use your solution as I only have a single default key in my registry. Also my folders stop at

    after which I get a folder that says ‘internet setting’, then the tree ends.

    Any ideas? I’m running winXP.

    Thanks in for sharing the solution anyway.

      Jay, if the registry key shown are missing then you have to recreate them. Let me know if you have trouble i can create on for you that is ready to be imported to your registry.

    Hi,
    Thanks a lot for the solution.
    I used the first step of the command prompt to solve the problem of invalid drive D: and it worked. But now in the option of my computer I see a new drive D: along with the C: drive (the existing local drive) which has the same files as that of the C: My question here is that is this going to be a problem for me when in future when I install new softwares?
    I also checked the registry keys by using REGEDIT command as per said and the pcitures shown by you and all of the entries were pointing towards C: as shown in pictures. But here my question is that should all the entries now be pointing towards D: or should be as earlier (i.e. pointing towards C:).
    Thanks in advance.

    good work man, this is really cool ;-)

    The command didn’t work for me, but the registry edit did. Thanks!!

    Any ideas as to what causes this problem to occur? I am very appreciative of the fix, but inquiring minds would like to know what could have caused this in the first place, as to avoid it in the future.

    In my case, the affected entries were pointing to an external western digital drive, to some Sync folder or something on there.

    Unfortunately neither of these solutions worked for me. I am attempting to fix the following error that comes up every time I try to install Adobe “Error 1327.Invalid Drive I:”. When I try the easy fix I get this: “Invalid parameter – I:C:”. As for the advanced fix, I have verified that all 5 of your registry points are correct, and I have also searched the entire registry for “I:” and corrected the two or three entries that came up. Yet still I get the same error message when I attempt to install Adobe. At this point I am baffled, and any help would be GREATLY appreciated!

    • Steph

      Nic, try;

      Subst I: C:

      noting the spaces in front of both the I and the C.

      • Nic

        It appears that this is the proper way to type the command (instead of getting an “Invalid parameter” message I get nothing–which I assume means success in the command world!) Unfortunately this did not solve the problem though–I still cannot install Adobe 9.2 (as I get the same Invalid Drive I: message.) That being said, a couple weeks ago my computer spontaneously starting recognizing pdf files using Adobe 7.0?! Seeing as I actually have a working version of adobe, I no longer have the necessity I had at the time of my original post. I plan to just stick with “what works” for now, and if it ever stops working again, I’m sure I’ll be back on the message board begging for help. :-) Thanks for trying though!!

    I was installing a Photosmart Plus All-In-One Wireless printer for my dad and kept getting this error. When we originally installed Windows XP on his computer, the (internal)USB SD drive reader caused Windows to install to the I: drive instead of C:(allocated to one of the SD card drives). This fix kept him from having to open the case and unplug all of the drives except his hard drive, or me driving 1 1/2 hours to his house and doing it myself. Thank you very much for this fix!

    WONDERFUL SOLUTION! Thanks so much! ATI Catalyst software 10.4 (April 2010) was not installing for me – it kept giving me an “install package failure” when I tried to update from the 10.3 drivers to 10.4. I searched the web fining no solutions that worked for me. I then tried to uninstall the Catalyst drivers NOT using the ATI uninstall tool, but using the “Programs and Features” under “Control Panel” in Windows 7. When I tried this, I got the “Error 1327. Invalid Drive :I” message. Googling that led me to your site, and the registry edits did the trick for me.

    ATI’s installation error is very uninformative – it doesn’t say anything about the I: problem. In my situation, I think the I: problem is because I recently replaced a failing hard drive with a new one. The failing drive worked well enough for me to transfer files over to the new one, though, so for about an hour I had two drives hooked up to my system, and one of them must have been assigned the drive letter :I. Once I removed that failing drive, I no longer had an I:, but for some reason a few mentions of I: remained in the registry. That’s what was messing ATI up.

    INVALID Drive G. After a month of this, I was so happy to find this site. After reading everyone’s successes, I was so excited. Now, very jealous, and feeling quite stupid, I am still where I began. The subst G: C: did not work. Typed regedit; see all HKEY_s; see no place to edit drive letter. (win7). iTunes told me to delete the old version, so now I have no access to the library, and the iPod doesn’t work (frozen in sync mode or something). Must have for my job. Help, please.

    • Nikolai

      Hi Anela,

      First of all i would like you to fill out the following:

      -When/Where does invalid drive G appear?
      -Have you tried the latest version of itunes for your windows 7 pc?
      -Is your Win7 an upgrade from vista or a fresh install?

      Regards,

      Nikolai

      • Anela

        Thank you so mmuch for the quick reply. So far, thank God, it’s only whenever I try to download the latest iTunes that I receive this message. The win7 is an upgrade (have had it for a while). I believe that the probleme is because, eaarlier in the year, I had an external (backup) drive to crash. Things were fine before then.

        • Anela

          Help me, please. I just can’t fix this thing.

  • Jay

    This worked for me. When I looked through regedit it looks like the WDSync program is what implanted all of the references to the G drive in my registry. I wonder if the WDSync will work after i change all of the references back to the C drive.

I am trying to install it via network…i can see it but when i try to add it is get the error message we all started with or error 0×00000643. PLEASE HELP!!!!

  • Dave

    Thanks!!
    It works for me too. My problem was with Adobe Reader 9.0. I was not able to update it or uninstalled. Any time that i tried i received the error 1327. invalid drive f:

    thansk again Nikolai for your post.

  • Lucas

    I did this and it all worked fine, thanks!

    i just have one question, under My Computer, i have both a C: and a J: drive. if i change something on one drive does it change on the other as well? also, how do i get rid of this (go back to only having a C: drive)?

  • Lucas

    I followed the first option and a duplicate of my C: drive appeared as the J: but my install still failed (AutoDesk Maya on Vista Home Premium). what can i do?

    • Nikolai

      you now have 2 partitions in your drive… changing somwthing on partition does not affect the other…

      To merge two partitions, youll have to delete both partitions and create a new one… You can do this using you Windows Installation Disk..

    The problem does not go away because I have mapped drives. The locations are perfectly valid. The solution is for software developers to NOT use registry keys where they don’t need to. I want to read PDF files. Nothing else. I ran into this with HP printer/scanner software as well. I don’t need printer/scanner software! I need drivers, and NOTHING ELSE.

    It is overly complex software solutions that cause these ridiculous errors and drive people away from Windows. Developers need to check their egos at the door and deliver only the essentials.

  • Zac

    I should note that in Windows 7 if you are using mapped drives the programs typically install under Admin mode, so it is not seeing your mapped drive. If you open you cmd prompt with run as admin option you can use the subst command with your C: and be in good shape. Still crapy programming on their part.

  • ALVIN

    THANKS! It works!

    This worked, thank you so much! I can’t believe it, but the My Pictures key was directed to the wrong place and somehow that affected whether i could install and uninstall programs or not.

    The Error 1327 Invalid Drive

    The fix is

    Subst (invalid drive letter): (existing drive letter):

    Yes this works on me too.

    Thanks for the blog and more power to it.

    Dude — this just saved me hours of time. I did NOT want to edit the registry file, where I know the problem lives. This seems to be a quick fix of the symptom. Tell me where to send you $25 (PayPal)

    This didn’t work for me at all. Neither of the fixes worked Win7 64bit ASUS laptop. I was successful in subst G for C and now both letters will bring up the same directories. But when I tried to reinstall my Sony Vegas I still got the Invalid Drive G message;

    Looked in the registry and saw nothing but C: pathe and %PUBLIC% and other percentage sign paths. What can I do?? Help!

  • jj

    the solution didnt work for me but the ulitmate fix did help.
    thank you!!

  • rick23ro

    Hi, I did the subst thing and now I have drive D and E with the same content, but in disk manager appears only the real drive D with the original data. How can I delete the virtual drive E?

    • rick23ro

      Solved after a restart. :D

  • Maiasaura

    I will pay this one forward, my friend. This was an annoying little problem that I never had time to figure out. I used to keep all my files on one computer, and one system kept looking there for files after it was retired. I would have to run down to the basement, boot up the old computer and connect it to the network. Everything works properly now! Yay!

  • Cait Ruane

    The fix seemed to be working–I’m on Windows 7, 32-Bit, but then I got a new error message: Invalid Drive E

    Can’t load CLScan.dll

    What the heck?

    Thanks for this… there was an external hard drive that had been moved to another machine, leaving some cruft in the registry.

  • Microman

    Thank you so much! Im running both on vista and Windows 7 and your solution fixed my error 1327 invalid drive! Thank you so much!

  • rbatters

    Hi I tried this and now when I try to do it again, it tells me that ‘Subst:’ is not a recognized as an internal or external command, operable program or batch file.

    • Nikolai

      Please type the command correctly. It should work.

  • Bubi

    I had the problem when reinstalling the HP Software. It was installed on my drive L:, and since it got removed, I needed it to install to drive P:
    But the software said: There is already an older version of software HP on L:Program FilesHP even though the drive itself wasn’t existent anymore.
    After searching in the registry for over an half hour, I found the registry Key. Finally.
    HKEY_LOCAL_MACHINESOFTWAREHewlett-PackardDigitalImaging
    a string called InstallFolder
    Either change it to your preferred new install folder, or delete the whole DigitalImaging registry folder.
    That’s how I managed to reinstall the HP Software to a completly different drive.

    Hopefully this will help someone

  • Maverick

    This fixed it for me. Iam using Windows Vista.

  • bamajs

    Fixed it for me, Win7 Pro. Thanks!

  • dhofstra

    These solutions did not work for me, but I had an identical error. I had moved special folders “My Documents, My Pictures, and My Music” to a networked hard drive. Apparently, after hours of research, i found out that the Windows 7 administrator does not have the same network drives available as the user who has administrator privileges. The install program is running as administrator, and cannot find the network drive.
    You can test if this is the problem very easily. Just run cmd.exe as administrator by right clicking it and selecting “run as administrator”. Once in the shell, try to switch to the network drive manually by just typing the network drive letter followed by a colon (i.e. X:). If you run a second cmd.exe without right clicking it as administrator, and try the same X: command, it will switch to that drive letter. This means that your administrator user can see the networked drive, but not the administrator (which is the auth that the install program is using)
    I read that you need to force Windows to make the network drives available to both the standard and administrator accounts automatically. All you need to do is run Registry Editor (regedit.exe), locate the key HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Policies/System, and create a new DWORD entry with the name EnableLinkedConnections and value 1.

    5 hours and countless websites later and this fixed it! thanks for saving me the $30 I almost spent

  • Azazel

    It should be noted that sometimes when this does not work or you fail to find an incorrect key that the problem may be found in a current install folder. In my case i was installing Napoleon Total War which requires the Steam program. Steam was already on my computer but was installed when i had an External HDD attached. No reg key problem in the main places you described but i did find one in the HKEY_LOCAL_MACHINESOFTWAREWow6432nodeValveSteam under the entry of Install Path. It was routeing my install to the non-existent E Drive.

    Thank you for your help on this matter, without this i wouldnt have been able to get close enough to the problem area and find my version to the solution!

  • Kaiak

    Thanks a lot it helps me on win xp with the quicktime setup!!

    LOVE YOu Bro!! Worked for me perfect

    Thanks a lot! This problem doesn’t let RDP works. Thanks again!

  • http://www.ikub.al Altini

    Also this fix brings up another problem, 2 different drive volume pointing to the same volume. If you unmount the fake volume then the initial problem rise again.
    One other thing that is important are the environment variables Temp and Tmp that maybe they are changed for some reason.
    The default should be
    %USERPROFILE%Local SettingsTemp
    and
    %USERPROFILE%Local SettingsTmp.

    Thanks

  • Nadia

    Problem fixed!
    Thanks

  • Doc Rock

    WORKS LIKE A CHARM. After 2 hours of troubleshooting,this instantly fixed the issue. As noted, my external drive’s letter was changed somehow and causing the fatal error. Thanks again SO much!
