This probably has something to do with file and registry virtualization
which only works with UAC on. If you want to run with UAC off, something I
don't recommend, you could try uninstalling the application with UAC on then
reinstalling with UAC off. The application may still fail. It sounds like
it's not really Vista compatible.
