[2021] Paradox Launcher Fails to update, CK3 fails to launch

There is nothing in those logs to say why the launcher - specifically bootstrapper-v2.exe - is not even attempting to update from that older version to 2021.6 . Normally we'd see a comms or permissions error. So I'm not really sure where to go from here on this one!

Maybe set dowser.exe and bootstrapper-v2.exe to run as the Windows Admin user?
