• 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.

Error 339


I have not used Obplacer_XML V 0.83.3 for some time.
Since then several changes and additions were made to my PC.

Today I wanted to use the tool again, but after starting the EXE I get the following error message (translated from German):

Error 339 (Unexpected Error:The component "msflxgrd.ocx" or one of its dependencies is not properly registered: a file is missing or not valid) in procedure MDIForm_Load of MDIForm1

I downloaded the tool again and installed it, same error. So it is not the program but something it looks for on my PC.

How can I repair?
