it helps to reinstall the program you want to uninstall. The act of reinstalling fixes all those little errors which make you can't uninstall them.
If you can't uninstall it immediately after a succesful install, it's time to contact the maker on how to do it. They might have it on the FAQ on their site, or they might have support by telephone or email.
Hope this helps.
