• 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.

MSFS Strange Error message after building a project

I'm trying to create a simple airport (which is not available by default) for my own "pleasure", i.e. to get to know the basics of ADE20 a bit better. After each creation run I get the 2 error messages as per the attached screenshot:


It seems that the compiler is looking for the Path "...\MarketplaceData" although there is no checkmark set "visible in store" in the Project Properties. Furthermore when I try to create this path manually before building the project, it will be removed during the building process. Also the Business.json is not created for any reason (maybe connected to the missing path?). I'm sure I'm missing something substantial, but what? :)

This is known since the last update. Ignore it. It is actually a warning and not an error.
