Installing the software is easy, but it can be frustrating when you encounter errors. For example, when trying to install Adobe, Kaspersky, or Microsoft Office, you may encounter an “Invalid Drive” error 1327. This simply means that the actual drive you’re installing the software on is not working.
In this article, we’ve focused on MS Office; however, the fix is not limited to Office. Depending on your knowledge, you should be able to apply the same approach to almost any application that returns this error.
Office installations have a tendency to force installation on specific drives that may be missing. In this case, you can use the SUBST command to redirect to the correct drive, or you can manually change the LocalCacheDrive location.
Causes of Error 1327 – Invalid Drive
The “Invalid Drive” error 1327 is an installation error that occurs when the drive used to install the program is invalid. This problem occurs mostly when installing Microsoft Office, but it can also occur with many other applications.
In most cases, this error occurs because the installer is trying to complete the process on an unallocated network drive. In this case, you can quickly fix the problem by mapping an unconfigured network location.
Error 1327 “Invalid drive” occurs for several reasons.
- Your registry credentials and network drive are no longer connected.
- Your network drive is checked Reconnect at login, and the system folder appears on the drive.
- Your registry key may contain incorrect values.
- You have accidentally changed the drive letter of your DVD drive.
- The system registry points to a temporary drive.
If you receive error 1327 – Invalid Disk, check the following ways to fix the problem.
How do I fix Windows 10 invalid disk error 1327?
Remove the drive letter using the command line
Use this command to connect and disconnect the drive letter from the virtual location. Disabling the letter should allow you to install the program without generating an error message. So here’s what you need to do:
- Go to Search, type cmd, and open a command prompt.
- At the command prompt, type the following line and press Enter:
- Substance /P (driver’s letter).
- Close the command line and try to install the program.
Reinstall the program
If this error occurs when trying to install a previously uninstalled program, there may be a conflict with the remnants of the old program.
You should make sure that the system is completely cleared of old or unused software. There are special tools that scan every part of the system and detect and remove leftovers.
Disconnect network drive
This solution works only if the PC has a network drive, otherwise stick to the previous solution. To fix error 1327, follow these steps to disable the network drive:
- Go to Search, type File Explorer, and open File Explorer.
- Go to that PC.
- Press Ctrl + F1 to open the ribbon with the tools.
- Under Network Disk Map, click Disconnect Network Disk.
- Try reinstalling your program
Reconnect the drive letter to a temporary location.
This method allows you to associate a drive letter with a virtual drive location. This way, the installer finds the appropriate temporary path and uses it to install the problem software.
Note: If the temporary path does not exist, you must create one.
- Run the command line as administrator
- Type [driver letter]: C:temp -> press Enter. Close the command line -> reinstall the program.
- Restart the command line and enter the command: subst /D [driver letter]: to remove the program shortcut in the temporary path -> press Enter.
Create a new user account
You can also try logging in with a different user account to see if the error continues to occur. If you don’t have a second account on your computer, you’ll need to create a new account.
