AFter an uninstall, it's possible there is still a folder in the C:\Program Files directory.. After a restart of the computer, you should be able to delete the folder.
If you can't, then try using the Windows Installer Cleanup Utility from the link below to ferret out any remaining registry entries and files from the program.
Hope this helps.
