Can you turn off UAC for a single app? [duplicate]

Yes, you can, using the Application Compatibility Toolkit: http://www.microsoft.com/downloads/details.aspx?FamilyId=24DA89E9-B581-47B0-B45E-492DD6DA2971&displaylang=en

There is a work-around that lets you create a shortcut that runs the program in administrator mode, without triggering the UAC. It utilizes the Task Scheduler. This is really a bit of a security hole, and it might be patched one day, but it is supposed to work for both Vista and 7. See this page from the How-to Geek.
