UAC bypass programs won't run on XPS13

I have a Dell XPS13 laptop that won't allow UAC bypass programs like UACPASS and WINAERO Elevated Shortcut to work. Both program run fine on a desktop and another laptop. Both programs will open on all computers. I am admin on all computers. UAC is set the same on all computers - almost always notify. All computers are running W10 Pro. It was a clean install on this laptop. It did not work with the original Home edition either. I can create a bypass task manually. UACpass simply gives me an error tone with no explanation and Winaero won't display the form on the Elevated Shortcut window. All systems are running on SSD's. The Dell is GPT, the others are MBR.
What else is there??? - These programs won't work for standard users so maybe they are not seeing me as an admin user, BUT WHY?? I am the ONLY user.
