• 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 v3 Does ACM create an add-on.xml file for P3Dv3?

Hi Arno,

I wanted to confirm if this is correct. If I install ACM for P3Dv4 it creates an a AutogenConfigurationMerger folder and an add-on.xml file inside it and places the folder into 'C:\{Documents}\Lockheed\Prepar3D v3\Add-ons' folder. . When I run P3Dv4 for the first time P3D asks if I wish to activate ACM and it updates the add-ons.cfg file with your entry in the ProgramData folder.

With P3Dv3 if I install the same way it does not create the above mention folder in 'C:\{Documents}\Lockheed\Prepar3D v3\Add-ons folder', and does not update the add-ons.cfg file. Is this correct? Thinking this is how is was for P3Dv3 but for P3Dv4 you added that?

This is using the ACM version you created for me (new entries at bottom), not the latest one posted for testing against Orbx agn missing, if that makes any difference.

Yes, the mechanism to install ACM via an add-on.xml file is for P3D v4 only. In the other versions ACM is installed in the exe.xml file.
