AccessViolationException

[CorellianAle]

I've ran into AccessViolationException after the initial setup window (where you choose online/retail and export folder path).

Here is the event log data:

Application: OBJExporterUI.exe

I am running it on a Windows 8.1 inside Parallels Virtual Machine for macOS.
I could be related to graphics and the my weird setup, but other complicated software runs fine (playstation emulators, various native rendering programs and so on). WoW runs just fine.
I am also using this setup for day-to-day C++ and C# development, so I can assist you with debug if you need, just not familiar with graphics, although I played with XNA so I might understand.

Hmm, interesting. My OpenGL implementation isn't really capable of handling different setups well yet. I've tested it on recent Intel, AMD and NVIDIA drivers but I guess Parallels runs its own graphics stack seeing it's a VM. The BindFragDataLocation call seems to be causing the access violation. Maybe I'm relying on some functionality that isn't by the standard. I'll take a look, thanks!
