Error message "please insert the Microsoft flight simulator game disc".
I got this message when I installed ‘bitdefender’. The firewall in bitdefender blocks the flight simulator 2020. To prevent this, go to ‘Protection’ > Firewall > Setting
Under ‘Default application behaviour’ select ‘Edit default rules’ For WiFi select ‘Allow’ from dropdown selection and select ‘Ok’
The FS2020 will load without the above error message!
What also triggers "please insert the Microsoft flight simulator game disc" is when you update the bios on your motherboard after you install the simulator. The simulator then thinks you've installed it on a different pc. Stupid, but true. This copy protection is several years old, and was a nightmare on older windows versions. Change bios, new hd, new graphic card etc. and the copy protection thought it was installed on a different pc. So several years later when it re-appears in a brand new flight simulator it's plain stupid. And why copy-protect it at all when it has to be online all the time with a genuine microsoft account?
How to fix this? I don't know. It happened to me when I updated my bios, and I had to revert back to the last one to fix this.
And a little tip at the end:
Check updates regulary on Microsoft Store. (Click the 3 dots in upper right corner and select downloads and updates)
So far I have received 3-4 updates here related to the simulator included a update for digital ownership which is a important part of the copy protection. Try this before you decide to uninstall/reinstall the simulator and see if this fix the problem.
