Hello,
First some words about my PC config : I have a dual boot and on system 2 I always have a P3D BASIC ( no addons) and I first update this system 2 so that I can check what is in the new folders and compare with the folders content of the P3d on system 1.
4.5 Installed, I had No problems . I started with the client and tested = all OK.
After I checked what was changed in the content … and so on. ...
