Fatal Error in graphic initialisation

Hi everyone,

i m getting a error in Graphic initialisation in my 3D Viewer Application
the error is in Graphic3d_WNTGraphicDevice class
but not able to locate the reason.

Can any one tell me on what all reason Graphics initialisation may fail???

thanx

Why don't you locate where it crashes in a debugger, that would make it much easier to find the problem, it is impossible to answer a question like "why does my program crash ?"

Does other OCC applications work ? in that case you have done something wrong in your code, if other applications fail also you may have a problem with your graphics hardware of some kind.

Maybe he must link to the libs located in ros\libd directory and build debug version of OCC-dlls. Then he could debug & trace the error in the source code of OCC. The full build of all OCC-packages takes arround 1 hr on a modern machine.

i was using OCC 5.0 till date and was working fine never had such problem
but in last month when i installed the OCC 6.2 and i started getting above error.But when i uninstalled the OCC 6.2 version the error doesnt cum any more.Graphic error i get is not only for my application but also it gives error for OCC Samples Exe's!!!
