What’s an “Error 1327: Invalid Drive E”?

Last week, I was trying to uninstall OneCommand Manager and VMware Update Manager from the same Windows 2008 server. I kept getting a pop window with a message “Error 1327: Invalid Drive E”. So like almost everyone, when something unknown pops up, we refer to the Internet. I saw several postings with regards to “Invalid Drive E:” and a few other drive letters. All seemed to relate to either a system folder mapped to a network driver, changing the CD-ROM letter or a possible corrupt registry key error. I took a look at my registry key settings and all pointed to the correct path. I then picked one of the links from my search and used Adobe’s help forum. I basically followed the solution 1 and it seems to have corrected the problem. Here is the link I used: http://helpx.adobe.com/creative-suite/kb/error-1327-invalid-drive-drive.html

Basically, go to a command prompt and use the DOS command called “subst” to remove the drive letter.

1. Select Start » Run
2. Type cmd command
3. Type the command as shown in the image above – “C:\>subst E: C:\” -and press Enter
4. Type exit to close the command window
5. Attempt to uninstall the OneCommand Manager

In my case, both OneCommand Manager and VMware Update Manager successfully uninstalled from the server.
