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 , Jessyde.

    I am Ivan, I will help you with this.

    Do you own the game through Steam?

    Hi, thanks for the help.

    I don't own the game through Steam; I have a boxed copy.

    Hi , Jessyde.

    I am Ivan, I will help you with this.

    According to reports published on Reddit and even on Microsoft's support pages, the KB5025221 update, released on April 11, brought performance issues to Windows 10.

    But if the update was in April, the problem has been presented now, a little strange. How do you post the event viewer of the game's error?

    Not only that, the update also caused some users to experience problems with printing services and some bugs in the system with Virtual drivers for using the system's graphics. The update, worth noting, had a fix that was letting the system recognize USB printers as multimedia device

    Hi Ivan,

    Does this fix related to printers also possibly fix my FSX crashes?

    And if so, which steps should I take in order to apply this fix to my machine?

    And if not, do you possibly have any clues on what I can do otherwise?

    It's also worth noting that the first clues appeared on the AVSIM forums around May.

    Hi , Jessyde.

    I even checked the case and even did the test without an update with the update apparently you are right KB5025221 and KB5025239 stop the game from starting apparently there are two updates that the error occurs when testing the steam version the game appears directx error directing to one software failure.

    Unfortunately, it is not giving the option to uninstall, at least in my test, KB5025239 is unable to uninstall the update.

    In that case, it would be a question of reinstalling windows to remove the update.
