A quick bump, with this question to the PMDG staff: I know that we still got no idea where the problem comes from (IVAO, MS update, ...PMDG ?) but did you have time to have a look at this random IVAP crash ? Same thread exists in IVAO forum. Thanks in advance,

I made two flight on IVAO Network, now with last hotfix everthing seem good, no crash , no exit crash, Transponder have connection to IVAP, nice, nice...great.I finnaly full enjoyed in great product. Thanks PMDG.I used internal IVAP, ENBseries ON. I also often shift from Full Screen FSX to Windows desktop and opposite, no crash...GREAT.

Installed latest hotfix yesterday flew ngx from LEPA to EGKK ivap crashed three times duing flight with little or no traffic at any time.I used internal ivap twice crashed twice although some distance between them then i used external ivap and ivap crshed on landing at EGKK.Did this flight as a test after installing new hotfix no joy. Regards Nigel Owen

blahh. I got CTD

I do too have experienced IVAP crashes. I just selected the option run as administrator and selected windows 7 compability but I haven't tested it.

Internal IVAP, ehh...

According to what PMDG team said in the "hot fix" topic the IVAP crash with the 737NGX is NOT due to the 737NGX and is NOT a bug.This is more the way IVAP is build, using FSUIPC instead of SimConnect.

Or to put it exactly !!

But didn't the IVAO guys make it perfectly clear that IVAP for FSX does NOT use FSUIPC? If it continues like this, each party blaming the other, we will never get a fix for this issue, I'm afraid.

I was fully able to to fly online with the NGX on IVAO up until the middle of august. This was after installing hotfixes and all was well.I had changed NOTHING on the NG but all of a sudden started experiencing crashes... IVAO... J'acusse!!!

I don't see how it can be solely IVAO, I never have crashes with the 747, md11 etc etc, so why all of a sudden does this happen.. This unfortunetly is exactly what happened with the "ghost planes" before "HIGHMEMFIX=1".. PMDG didn;t want to get involved at all, until ******* came along :)

Don't forget MS windows updates in the meanwhile ...

I did not have CTDs with IVAO and MD-11 and J-41 (and the rest of the fleet).And I can not make any connection between MS Windows updates and FSX crashes.To put it that way - IVAO doesn't like the NGX and it appears we'll need someone like ******* to trace the issue. PMDG guys fly with VATSIM and obviously don't care much about the compatibility with IVAP software. Correct me if I am wrong...

Finally after Hotfix and remove of ENBSeries, no more IVAP crash for me. :DFor my setup ENBSeries is the Problem, disable doesnt work, still crashes. remove it completedid the trick for me.

ok again fsx crashes again during online flying at ivao :(..same unknown module as before. seems not fixed

My first flight with Ivap internal, LEMD-LEPA, all perfect, but exiting runway and passing transponder from C to S, Ivap crashes!!! There is a way to minimize Ivap external?
