Go to
http://www.revouninstaller.com and download it (completely free)
As long as the program in question appears in your list of problems, Revo has always, without exception, worked for me and my customers in removing software. When prompted, choose Advanced as the removal method and even if the built in uninstaller fails, Revo will remove ALL traces of the program.
9/10 times the built in uninstaller leaves rubbish behind, I only ever uninstall with Revo.
