WindowsError: exception: access violation reading 0x00000000

MlRawViewer doesn't start for me. I tried V1.4.0 and v.1.3.3. No difference. If I doubleclick on mlrawviewer.exe the file selection comes up. After selecting an MLV nothing hapens. No processing running. I also tried dragging the mlv over the exe but also nothing happens. The MLV's work on another (win7) PC. I'm on Windows 8.1 64bit, Catalyst 15.9, AMD Radeon HD7800. Tried running as admin too.

Here is the log:

Hmm.. hard to say what the problem is without being able to reproduce it (I don't have access to Win 8.1 machine with AMD).

I suppose you have tried some other OpenGL programs on that machine and they fine?

Andrew. Thank you for your quick reply. Yes, OpenGL is working fine. I was hopeing the error already came up and someone has a solution. It's maybe my machine only.

Hmpf. I guess it really was just my machine. Installed Catalyst 14.9.1 beta and all 1.4.0 and 1.3.3 work fine! I guess the reason is not the 14.9.1 beta driver but a bad installation of the version before. Though strangley I had no other issues. Even testing OpenGL worked fine. Anyway you can close that issue. And thank you again for your amazing work!!!
