Hello Folks,
So recently I have had alot of people message me about an issue with P3D V3 throwing an error "error creating child window" and or crashing due to a recent Windows 10 update. I did a bit of investigating and saw that the issue was caused basically due to some invalid string and return data within the included .NET 4.7 update. After reaching out to a friend whom is an engineer with MS and him looking into it, I was informed that the November 14th patch would resolve the issue, but it didnt of course.. Well, here is a fix that i've tested with a couple of friends experiencing the issue and it resolved the error from coming up and crashing. It's as simple as removing .NET 4.7 and I have included the simple instructions below;
Step 1: Click on your start button, search for and open "Control Panel"
Step 2: Click on Programs
Step 3: Once in Programs, Click on "Turn Windows Features On or Off"
Step 4: Once the Windows Features window opens, Uncheck ".NET Framework 4.7 Advanced Services" and then press OK.
This should remove .NET 4.7. Afterwords, you may need to reboot your computer (I would anyways). After the reboot, run Prepa3d and the child window error should not occur! During testing, I also loaded all the addons I could (Such as Active Sky, vPilot, and a few others) but thankfully very little programs are .NET 4.7 dependent therefore there should be no impact to any other programs.
NOTE: In the event that Microsoft get's it's sh** together and they release a working update, you can easily re enable/install .NET 4.7 by replicating the steps above with the exception to the last step in which you will enable the checkbox and press OK.
Have any issues or questions? Send me a private message and I will be more than happy to help. I'll be looking into the FSX-Steam issue that has recently came up with the latest update and once I find a fix for that, ill post in the appropriate board.
