Thank you for getting back to me!
My user account on this computer has local admin rights, but I don't think I clicked "Run..." during the setup process. So, how can I restore the correct permissions? Also. if "Run.." is required, why is there a checkbox to skip it in the first place? That should be fixed then, right?
I have marked "Save all settings to INI file" now and will report back if that makes any difference.
Last, but not least, I also did a reinstall with the latest version and guess what, the "Start..." option has disappeared and it is now mandatory to run the app at the end of setup. I am going to reboot now to see if the problem is gone. Wish me luck! :)
