Program and Features in the Control Panel show the list of installed applications on your system. You can easily uninstall those apps from that page. But, sometimes while uninstalling the apps, you may see this annoying error message, ‘Error 1327. Invalid Drive error’ on the screen. This problem usually occurs due to the corrupted drive or a network drive from where the uninstaller is trying to uninstall the app from here.
Fix 1 – Temporarily Using SUBSTR command
Another way to fix the issue is to substitute the drive letter in the error message with the OS drive letter (usually ‘C:’).
1. Pressing the Windows key+S keys together. Type “cmd” in the search box.
2. After that, simply right-click on the “Command Prompt” and click on the “Run as administrator“.
3. When the Command Prompt window appears on your screen, paste this code and hit Enter.
subst wrong drive letter: OS drive letter:\
Example –
Suppose the drive letter you are seeing on the error message is “K:“. Usually, the OS drive letter is “C:”. So, the command will be –
subst K: C:\
Once the command is executed, restart the system.
Fix 1 – Correct the path from the Registry Editor
This problem occurs when the uninstaller is trying to uninstall the app from a different drive.
1. Right-click on the Windows icon and click on “Run“.
2. In the Run terminal, type “regedit” and click on “OK“.
NOTE –
In the Registry Editor opens up, click on “File” and click on “Export” to create a new backup on your computer.
If anything goes out of hand while altering the registry, you can easily retrieve the registry back to normal.
3. On the left-hand side, navigate to here –
Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
4. On the right-hand side, you will notice several entries.
5. Now, check the ‘Value data:’ for every key on that list.
Note if there is any ‘Value data:’ which has an F or any other letters except “C:” (your OS drive).
6. Double click on the particular key on the right-hand pane to correct it.
(Example – As the ‘Cache’ key has the incorrect value data on our system, we are going to modify it. )
7. In the Value Data: box, replace the wrong drive letter with the OS drive letter (“C:” usually).
8. Then, click on “OK” to save it.
Close the Registry Editor screen. Restart your computer. Then, try to uninstall the application from the Program and Features.
