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?

    sometimes a flight can be do but it's a good luck .

    It is still installed, i just make sure not to have it running. That fixed it for me.

    But do note that API.dll crashes on STARTUP are usually related to corruption to either the sim or something on your pc.

    but I don't open anything, I don't use any addon, I launch FSX clean and it always gives me the same api.dll error.
    But did you actually uninstall REX from your PC?

    Hi,

    I've always used REX too until it gave me the API.dll ctd everytime i tried to fly.

    Could be the same for you.

    yes of course I have a lot of programs in the background (IVAO, Acars Virtual Airline, Navigraph, FsxWx...) but they have always been there and they have NEVER caused me problems.
