Selectively deactivate UAC without running as administrator

Hi all,

I'm facing the following issue : I'm trying to run two programs at the same time but are both troubled by the UAC level.

1. Program 1 does work when the UAC is at level D (lowest) and doesn't work otherwise. In any case, it bugs if ran as administrator
2. Program 2 does work when the UAC is at level C (just above the lowest) but not if the UAC is at level D. (how strange !)

Is there a way to keep UAC at level C (so that programm 2 works well) and bypass it for Programm 1 without running it as administrator ?

Any help would be gladly appreciated !

Hello Brink,

Thank you for your answer. I tried these method, but the very problem is that my programm doesn't work when launched as administrator.

Is it possible to avoid UAC without runing as administrator ?

Thanks !

The two programs are driving some scientific instruments.

I don't get a proper error message, but both indicate in their own ways that they are unable to communicate with the instrument. Has the UAC any consequence on USB communication ?
