Log on with an Admin account. Find the executable, right-click it, choose Properties, and hit the Compatibility tab. You can then click the Show settings for all users button and mandate that it runs with Admin-level power no matter who runs it. You can also pick a compatibility mode in there... for example, I have an old image-editing program that I set to Win2000 mode to overcome most of its issues with Vista x64 .
What program(s) is/are giving you problems, out of curiosity?
