On PC of course 
Perfect I will try this as soon as I´m back at home. Looks like this time the Flight Sim 20 is not launching after emptying the Community folder 
I tried before leaving but no luck this time.
Removing Comodo firewall might have caused some serious problems on my current Windows installation and the Flight Sim.
Comodo was suddenly deactivated because the trial phase was over a week ago or so, and I could not delete it after this.
While it was deactivated it was not possible to install GOG to download Witcher 3, it was not possible to run any VPN, and it was not possible to install another firewall.
Hmmm… After the removal tool for Comodo Firewall and after resetting the original Windows firewall with Command prompt + “netsh advfirewall reset” FS20 asked during the last launch if Windows firewall should allow FS20 to go online, and I allowed public and private network.
Since this time the Flight Sim is not launcing anymore.
