Thanks Louise Great to hear you got it sorted. I really didnt want to reinstall windows so I battled on.
I Finally got it to LOAD!
After crawling through pages of tips and tricks I have found a solution to my CTD on loading screen issues.
Only problem is I'm not sure exactly what fixed it but this is the Process I did.
- Uninstalled MSFS 2020 and Restart PC
2 Uninstalled Xbox App and Restart PC
3 Set App language Settings to US English (this is a different setting than the keyboard and Display Language. It is in the windows settings app.
4 Installed windows sdk and Restart PC
5 Installed Xbox App and yup Restarted PC.
6 Logged in to Xbox app and searched for Flight Simulator.
7 Installed MSFS 2020 (from the xbox app) then Restarted PC
8 Now I Launched MSFS from the start menu NOT THE XBOX APP. Right click and Run as Administrator.
The Desert scene came up like usual but instead of the expected CTD up came the installation manager and so far so good I am downloading content.
I really hope this can help Others, Good Luck
Update: After about 8 hours of downloading the extra content the Sim works. and it does look amazing. Two weeks of frustration getting it to work seems a little over the top but I'm not complaining now :)
