Sage 2019 on Windows 10 32 or 64 Bit - having issues running accpac (not as administartor)

Sage 2019 on Windows 10 32 or 64 Bit - having issues running accpac (not as administartor) - not even getting a Sage accpac login screen the splashscreen comes up and then disappears. Does not work in Win7 Comaptibility mode unless you are troubleshooting the compatibility mode otherwise if you set to compatibility mode on icon properties it does not work. Tried giving user full rights to accpac share, registry, program folders as well as using default accpac program folders. Tried with shared data being remote and local. Event viewer suggests issue is with loading cato3msk.dll.

Client security policies dictate not being able to run as administrator as a valid option.
