I've been away from the sim for a while but decided to hop back on today and I'm now experiencing a problem I've never had before. Whenever I start P3D and click on change aircraft or location, the sim crashes to the desktop after a few seconds with no pop up. The only things I've done were update QW 787, ActiveSky, and P3D from 4.4 to the latest 4.5 HF2 (only client and scenery). I can't figure this out and about to do a a whole uninstall and reinstall...

Any help would be appreciated.

Are you selecting an aircraft or change of location at the Scenario screen? What happens if you just press OK and enter P3D with the default aircraft and location?

What is your startup aircraft? PMDG specifically state their 737 should not be a startup aircraft. Maybe the same applies to the QW787.

Yeah at the scenario screen. I don't even get to click on a new aircraft or type a new location before it crashes. And the default F-22 is what I have for start up aircraft. If I load from the default scenario, it loads just fine. And then going to select a new location or aircraft, crashes again.

Okay, so if you go with the default aircraft and location it’s fine until you try to change either.

Try renaming Prepar3D.cfg and change extension to cf#. That will force the sim to generate a new one. If that fixes it all well and good. You can find it in:-

C:\User[yourname]\AppData\Roaming\Lockheed-Martin\Prepar3Dv4.

If that doesn’t work clear the shaders folder. I can’t remember the location. Google “delete shaders folder P3D”.

Time for bed over here. Catch up in 9 hours.

Just a few clicks away from main AppData folder - C:\Users\X\AppData\Local\Lockheed Martin\Prepar3D v4\Shaders

Contents of shaders folder should be cleared entirely after P3D update. As mentioned by Ray, prepar3d.cfg must be rebuilt after update.

Tried both, same result with each. Really frustrating.

Had the same, similar issue, but it wouldn't make it to the splash screen, same updates performed except for scenery, only client, reinstalled the Fsuipc module and all is well, just a thought.

Bummer, tried this and same result. 

Ok Update:

I've uninstalled P3D fully and reinstalled. Same. Exact. Issue. FSUIPC doesn't affect anything. It also doesn't crash until my mouse goes over an aircraft in the list and highlights it, not even clicking. Also does this any time I select a drop down in options or anywhere on the startup screen... How could it still be happening after a fresh install?

Have you tried installing app crash view and seeing if there is an error when it crashes ? https://www.nirsoft.net/utils/app_crash_view.html

I may have solved it by uninstalling the latest windows update. I'm now able to load a plane and fly... fingers crossed.

Well done. It will help others if you name the update you uninstalled and post your current windows build number.

uninstall instances of Microsoft simconnect in your add remove programs and run the msi installers in the p3d\redist folder (but NOT the Japan and Russia folders, do all others)

Is this the solution to the original problem, or something else?

I had the same problem, associated with the .NET updates. I had to remove the update twice (since Windows insisted on re-installing it a week later), and then magically on the third update everything works.

If I remember correctly the crashlogs indicated a D3D9DLL error, which is part of the .NET framework.
