Have you tried setting up TestComplete/TestExecute to Run As Administrator? There are subtle differences between being an admin and actually running an application with administrator level access. Even as a local admin on my workstation, if I have to do something that requires admin access, it still prompts me. This is the UAC stuff from Windows 8 and 10. See if that works.
I tried running as administrator and this creates a different issue. When i open TestComplete and try to select my project it can not find it. The project is stored on a network drive mapped to S:
I can open Window Explorer and browse the S: drive but TestComplete does not see it if I run TestComplete as administrator.
Just means that the administrator doesn't have the S drive mapped. Instead of using the mapped drive name, try using the FQDM mapping of \\<servername>\<sharename> etc
