I found a good clue in a log file posted it here:
To summarize that post, the Intel DSA log shows
"11/22/2020 20:15:58 -05:00 41596:1 Error DSAServiceHelper.Program Main () Install: Failed for 29919 (41596):: System.Exception: Failed to restart process (C:\WINDOWS\system32, file:///C:/Program Files (x86)/Intel/Driver and Support Assistant/DSAServiceHelper.exe, install 29919)|| at DSAServiceHelper.Program.RestartAsAdmin(String cmdLine)|| at DSAServiceHelper.Program.Main(String[] args) { }"
And I may have caused the problem when I switched my Windows account type from Administrator to Standard.
I am seeking a way to allow DSA to elevate the installer as needed while keeping my account a Standard type. Is this possible?
thanks
