Didn’t work for me either...you need to use “Your Uninstaller” [software, check on either any file sharing site or torrrents, and you are likely to find it] or do the following:

1.delete the autodesk folder in program files
2.search in system drive [C:\] for any references of autodesk folder and delete them.
3.search the registry and delete any references to the term autodesk

and you are done.

Hope this helps !
