I saw that the free upgrade to the Logos 6 engine was available, so I made the free "purchase", then started my Logos 5, and it proceeded to run the update. In the process, it gave an odd error message "The selected user does not have sufficient privileges to complete the setup. Please choose Administrator from the Run as... dialog." But the installer continued, so I thought it would work.
But after the installer finished, Logos 6 won't start. It gives me the Logos 6 splash screen for some seconds, then quits.
I tried uninstalling Logos from my computer, then installing it again after downloading the Logos 6 engine. This also ran the installer again, produced the "selected user does not have sufficient privileges" dialog, ran for a while, and Logos 6 still will not start.
I've tried right clicking on the LogosSetup.exe and choosing "run as administrator", that produces the "selected user does not have sufficient privileges" message right away and nothing else happens.
