Hi, I've just updated from p3dv4.1 to .3 and everytime I try to open the sim, it just shows this window forever: https://prnt.sc/k1ynf6

Does anyone know how to fix this?

Thanks,

If the issue is determined to be caused by an add-on, you will likely want to reach out to the add-on developer for direct support. If they need any support with development, they should not hesitate to contact us.

I did everything regarding the topic you sent and nothing happend. It was probably not an add-on beacause I uninstalled all of them, but just in case, I uninstalled everyting regarding p3d and I am now installing the sim again.

Thanks for your help, :)

Strangely enough I have just encountered the same problem today. It seemed to be caused by an addon airport that I had deleted using the Windows 10 "add/remove programs" while still being listed in the P3D scenery library. I had to re-install the airport, fire up P3D, delete the entry in the P3D scenery library first and then uninstall the airport again. After that it opened normally.

Regards.

Luckly I found the solution:

''Delete the following generated folders/files. This will result in any add-ons being removed/disabled.
%PROGRAMDATA%\Lockheed Martin\Prepar3D v4
%LOCALAPPDATA%\Lockheed Martin\Prepar3D v4
%APPDATA%\Lockheed Martin\Prepar3D v4''
