    If a program needs to be run as administrator, it should be manifested as such when it was compiled. Programs needing administrative privileges should request them when started normally, using Shell.Execute(), from your code or via a Quick Action. If the program does not show the UAC dialog when started, then update the program so it conforms to current Windows software guidelines.

        As I said, you need to correct "the program", which previously you referred to as "my executable file". Again, if this is your program as you claim, you should definitely correct it, making it ask for elevation when it starts, via Shell.Execute(). This is how things should be done since Windows Vista, which was released years ago.

        Running a program under credentials of an account with administrative rights on the computer is not the same as running the program "as administrator". One thing refers to the credentials used to log in and run the process on, the other refers to user elevation, which is another user token. Even an administrator needs to confirm the User Account Control request for elevation, when running a program which needs to perform changes to the computer, or the operation will fail. This is what you can get when you use File.RunAs() even using an admin account:

        So now that you know how to do it properly, it should also be clear how you can run this program via AutoPlay Media Studio, although in a clumsier way: You need to manifest the AutoPlay application to be run with the "Require administrator" setting. The user elevation is requested at the program start, via the User Account Control dialog. If the current user is not an administrator, then credentials of an admin account must be provided before the elevation can be performed. Once the process was elevated, run "your executable file" with File.Run(), so the child process inherits the administrative rights previously granted via the UAC.
