FSX Crashing after connecting to vPIlot

After I installed the Airbus X A320/A321 I keep getting this error ************** Exception Text **************

My idea is something to do with the model matching or sim connect? Either way its getting on my last nerve and has stopped me from doing flights I could easily do.

Can you post the data from the Windows Event Viewer. The 0xC000014B is a .NET error. Most common causes that I’ve seen for that are the uiautomationcore issue, a bad terrain file, a corrupt AI file, or something wrong with a flyable add-on aircraft. You’d have to get the faulting module name from the Event Viewer entry for that error/crash to troubleshoot more.

Several posts on the topic over the years (Programmable Search Engine). It’s a very elusive error to find/fix. Best recollection I’ve had (from years ago, almost no one uses FSX anymore) is that it’s a broken communication pipe, usually due to something (like addon aircraft or AI) making a Simconnect call that’s not possible/successful. You’ll likely find that the faulting module is FSX. After FSX crashes, vPilot reports the error (in other words, vPilot is REPORTING that there’s an error, it’s NOT CAUSING the error).

If you FULLY uninstall the Airbus X A320/A321, does the error persist?

After some continuous research and still crashing, I don’t think the problem is any aircraft I looked at the event viewer and the faulting module was the api.dll

As an FSX user myself I am having this same issue, I’ve tested vPilot and swift to the same CTD. On vatsim in certain regions I get the CTD with the API.dll crash log in the event viewer (for instance the Vancouver straight now which is strange…), I’ve noticed my VAS usage slowly goes down until it runs out of memory, And thus it spits out the error. I’ve played with my model matching to see if that is the issue but it isn’t. I have not uninstalled the Aerosoft a320 to see if that is the issue as I do have it installed currently. But my guess is that it’s just a fsx problem considering it is approaching 18 years old now, and it is 32 bit. I’ve done a full sim reinstall and a reformat of windows and it still crashes. Just wanted to say something about this as it’s kinda dead haha. this is just my take on it. It’s confusing.
