FSX API.dll

Hi,

Lately my Microsoft Flight Simulator X has been crashing with API.dll as the faulting module.

This is probably caused by a Windows update dating back from April.

There is absolutely nothing one can do to fix this, unless rolling back the update is possible, which it isn't.

The update that's causing the crashes is most likely "KB5025221".

What can I do?

    Hi,

    I recently tried running FSX again after the recent windows updates but I still get the API.dll CTD from a clean install of the game. Did you manage to find a fix?

    Thanks,
    Matt

    Hey,

    Another update on my side:

    I successfully completed 1 long-haul flight of 8 hours, and 2 short-haul flights both around 1 hour.

    The issue seems fixed for me after I stopped using REX Skyforce 3D.

    If I get the API.dll CTD again, then I'll update here.

    I installed the latest July 25, 2023—KB5028244 update but I ran into the API error when the sim was 80% loaded so it looks like the error persists for me.

    It would be good if Microsoft could provide a workaround or fix for this

    Hi,

    I just managed to complete 2 flights, without FSX restart, on VATSIM. Normally I run Active Sky 2016 with REX skyforce 3D. For these 2 flights I only used Active Sky and no REX. Maybe for me that was causing the issue, but only 2 flights have been done, so I can not say for certain.

    Hi all,

    I've also struggling with the same error and do not have an option to uninstall the update.

    Are Microsoft planning on issuing a hotfix for this?
