CC mentions admin password required but no pop-up - GenP

Ive followed the guide before without issue but had to do a fresh install, used adobe cleaner tool etc.

Followed the guide from fresh and did each step, but when I’ve done the CC install, then patched it, then i re-open as admin and look to install any apps i get a pop up saying “admin password required - check for an OS prompt and follow the instructions. We will need your system administrator password to continue.”

However i do not get any OS pop up. I have ensured CC has full access on the exe security tab. Not sure where to go from here. Did another fresh install and same issue. Cheers
