I recently updated a stand alone application from Maya2009 (x86) to Maya2012 (x64), but I have an issue where some of the files we have crashes the application when calling MFile::open. I get an “Access is denied error” and I can’t catch it.

It happens when loading the scene, and not with every file, so I have to think that something in the scene is causing this. I have tried to delete history and optimized the scene.

CRASH!!!

Anyone experienced something similar?

Update:
I installed and compiled with Maya 2011 (x64) and don’t have this problem with that version. I guess I’ll just go with Maya 2011 and jump directly to Maya 2013 when that time comes.
