.NET Runtime error after installation of 777

Recommended Posts


after I installed the 777, I started it up and loaded the Cold & Dark state. Then all displays went dark and stayed dark even after ext power / APU was present. I then exited the Sim and I got the first message that P3D stopped working. 

 The problem spread to all other a/c, default and payware (AS320, QOTSII). Everytime I start a scenario, when reaching 100% on the loading screen P3D crashes, first the .NET Runtime Frameworks, the P3D itself.

I run Windows 10 and have P3D on a seperate SSD and installed the 777 as admin. 

I tried reinstalling the 777 and also the P3D client, but nothing changed.See below the error from the event viewer:

thank you so very much! 

The Windows Update indeed was the reason for the crashes. I would have never suspected this. You saved me from wiping P3D an setting it up again.
