How can I fix Error 1327 invalid drive?

  1. Remove the drive letter with Command Prompt
  2. Reinstall the program
  3. Disconnect network drive
  4. Reassociate the drive letter with a temporary location

1. Remove the drive letter with Command Prompt

  1. Press Windows + R, type cmd, and hit Ctrl + Shift + Enter.
  2. In the Command Prompt, type the following line and press Enter (Substitute your drive letter for P):
    subst /P
  3. Close Command Prompt and try to install your program.

Your command will allow you to connect and disconnect the drive letter to a virtual location. Disconnecting a letter should allow your program to install without generating an error message.

2. Reinstall the program

If this error occurs when you are trying to install previously removed software, then some of the leftovers of the old program might create a conflict.

You should clean the system from old or unused software thoroughly. There are specialized tools to scan every part and detect and remove leftovers.

We recommend you use one of the best uninstaller software as they can remove every file related to the app you want to delete, thus allowing you to reinstall with no issues.

3. Disconnect the network drive

  1. Press Windows + E to open File Explorer.
  2. Find the Network drive.
  3. Right-click it and select Disconnect.
  4. Try to install your program again.

This solution will work only if a network drive appears in the File Explorer; otherwise, stick with the previous solution.

4. Reassociate the drive letter with a temporary location

  1. Press Windows + R, type cmd, and hit Ctrl + Shift + Enter.
  2. Type the script below and hit Enter (replace Drive Letter with your actual drive letter).
    subst [Driver Letter]: C:temp
  3. Close Command Prompt and reinstall the software.
  4. Again press Windows + R, type cmd, and hit Ctrl + Shift + Enter.
  5. Type the command below and hit Enter to remove the software’s association with the temporary path:
    subst /D [Driver Letter]

This method lets you link a drive letter to a virtual drive location. In this manner, the installer will locate the respective temporary path and use it to install the problematic software.

Note: If the temporary path doesn’t exist, you must create it.

These solutions should suffice. However, in some extreme situations, you must create another user to correct the problem. You can also try signing in to another user account to see if the error still occurs.
