It seems the same issue appearing in different guises; this is a common solution: http://www.itninja.com/question/another-not-a-valid-short-file-name-problem

Not sure if an answer has been given to this issue and I hope I am not being redundant, but I had this same error and the problem was an invalid User Shell Folder under the registry key, HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders. The element "My Pictures" was pointing to a drive letter that is no longer available. I reset the data to %USERPROFILE%\My Pictures, reran the set up program that was failing and no more error.

Finally, consider you can avoid manually fixing the Registry by running a scan-and-fix tool as suggested here:
