Program won’t uninstall

I am running Windows Vista and trying to uninstall a program however when clicking on the program using the Windos uninstall feature the uninstall option does not appear. The program does have an uninstall feature but that does not work either I receive an error message that states “Aborting patch. Could not find the apps.conf file.” I don’t want to have to mess around with the registry. Will just deleting the program files do the job?? I tried using Revo Uninstaller but it never located the program. Thanks…!
