Removing programs under administrator rights

I have problems removing a time restricted program (Sony Vegas) using add remove programs on Vista Home Premium. When I try to remove it I am told that I have to contact my administrator ( ME) as I dont have permission to remove it. There is no uninstall option on the program. Can anyone help?

Thanks for the suggestions.
I managed to get rid of the unwanted programs by temporarily disabling UAC( user account control):)
