Avast Driver Updater installed, but doesn't work?

UPDATE: Logged into Avast Account, found, downloaded and ran installer, entered activation code, now working fine.
#########################################################################

Read through Forums, found and ran “C:\Program Files\AVAST Software\Driver Updater\SupportTool.exe” - took forever to complete, but eventually did. Attaching screen shot for what happens when trying to run, (even Run As Administrator fails with same).

Have installed and used this on another Win10 Pro workstation (laptop) fine, but on this desktop Win10 Pro workstation, not.

Are there any human readable log files kept any where?

Ideas? Have a link where I can perform a fesh downloadable Windows 10 Pro installer?

Thank you!
