Revo Uninstaller
Home page: http://www.revouninstaller.com/
Open source: NO (AFAIK)

Helps you get rid of broken programs that you cannot properly uninstall and cleans their remnants up.

Worked for me.

There is a free and a paid version. The free one should suffice in most circumstances. I can't comment about the paid version, which I do not have.
