Version 5 will not run in Admin mode

[ColoradoHiker]

I just updated to the latest version of BI tonight. Since then I'm not able to run BI v5 in admin mode. Windows 10 Pro 1809. This is a dedicated PC with only 1 user. That user has full admin rights. I right-click on the BI icon and "run as admin". It only runs as non-admin. I have set the service to run using this admin-level user. No difference. No matter what I do I am unable to run BI in admin mode.

Any help sure would be appreciated!

TIA,
Jim
