• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

P3D v4 Stops immediately with message


Resource contributor
Thanks, Jay.

I have no aircraft in add-ons.xml’s, only scenery.
Piet, AIFP doesn't know this. So, it must open every add-on.xml file it can find. You can download Development Release 3.2.09(k) from http://stuff4fs.com. It seems to solve such problems for everyone else.

Now I discovered the following:
Each time I try to tick V4 it shows the message and abends.
Then I went trying working with v3 ticketed. I can add AI-aircraft to a plan from my AI-aircraftfolder. As soon as I try to add one directly ouit of the V4-aircraftfolder, the message appears and that aircraft is not added.
Then compiling that v3-flightplan works well.
Then after restart of V4 to let the new traffic.bgl be added to the active scenery, the traffic works perfectly, all 6 planes from the plan show up. See screenshot
Does this help looking into the cause of the error?

Piet, I think its time to go back to "square-1".

The problem with reading addon.cfg files is resolved in Development Release 3.2.09 (m). If you are not using that development release, please do so.

That problem has nothing to do with adding aircraft into flightplans.. So, if you have an issue in that regard, it is an entirely different problem.

So, let's go back to the beginning. Tell me what you are trying to do, the symptoms and what you have done to that point.

Now it seems to be allright. I installed 3.2.09 again, now especially paying attention to Development release.
Then I also made the Prepar3D-folder unaccessable (by renaming).
Then I started AIFP and only the V4 choice button was present and on.
Then opening, editing and compiling existing ai-plans went well.
So end of the search for a solution.
Thanks for your patience and tips.

Thanks for the confirmation. Generally, its a good idea to use development releases, especially when a problem you are experiencing is being worked on.
