Error message creating child window

[FLYING TIGER]

Hi,
After having a little trouble with Ezdok v2 many things start to go wrong. P3Dv3 doesn’t work after
selecting an aircraft (or later on in the proces)
It goes like this:
I start P3D and the normal “Scenario Setup” screen appears. I select an airplane, click OK. Sometimes it goes already wrong here and the message “Error creating child window” appears. https://www.dropbox.com/s/f9v7734bik4cw ... 0.jpg?dl=0
Then 2 things can happen. Either the next screen appears (so far so good), or P3D closes with the message “P3D doesn’t work anymore (Free translation from Dutch-don’t know if this is what you see in English)
https://www.dropbox.com/s/7kykzkmrkghur ... r.jpg?dl=0
In the first case I click Ok and then it takes some time until I’m in the cockpit of the selected plane (in this case it’s the new Alabeo Moony). Or sometimes P3D shuts down, its different all the time.
Normaly, when in the cockpit, I can click on Shift + a number key (above the caracter keys) and then a little should pop up where I can select a few things fort he set up of the cockpit. Also in the A2A aircraft, and others, you could do those things. But eacht time I do so the same message appaers “Error creating child window”.

Somethimes when I click Ok in this message the message disappaers with no further outcome (except that I can’t use the shift + ? possibility) but sometimes P3D will shut down with the message “P3D doesn’t work anymore” once again. What can I do about this issue? Anybody have a solution? Or is it possible to reinstall P3D without having to uninstall P3D and all addons (ORBX,GTN750,FSUIPC4,EZDOK etc.) and then to reinstall all addons again after installing P3D? Not looking foreward to this because it takes a whole lot of time, and many things can go wrong during this process.
It is also impossible to select another plane once I’m in a scenario. Then the same error message appears without anymore I can do. Sometimes when clicking OK in that message P3D shuts off.

I hope my request for help is clair, because I’m not a well seasoned simmer and certainly no computer wizzard!
Awaiting a positive reply,
Kind regards,

Hello Martyson,
thanks for replying. I did have a quick look, no..I had a long look :-) But as I mentioned I'm a total computer no-no and everything in those posts is hocus-pocus for me. They are talking aabout things I even never heard of. Sorry to say but it's the thruth. Many of the posts are refering to something called WIN 10 KB 4038788 and user.dll 10.0.16299.64.
I wanted to check whats on my system but haven't got a clue where to look. The only thing I could find via the control panel (I think that's wath it is called in Englisch) is the following. Can somebode tell me where I have to look for checking these 2 indications please?

Why not go to the post I mentioned in the main P3D support forum and add your information, as they are collecting data from pilots using P3Dv3 and getting the Child Window error.

You mentioned:

Also, in your post here you mentioned using the Migration Tool. Do you till have it installed on your PC?:

No,I banned Migration Tool from my system, and I use only legal addons (just to let you know).
