Q: Game Error OGRE EXCEPTION line 91
A: If your error looked a little like the spoiler below, then you may be missing DirectX, or it hasn't installed correctly. OGRE EXCEPTION(7:InternalErrorException): Could not load dynamic library .\RenderSystem_Direct3D9. System Error: The specified module could not be found.
in DynLib::load at
C:\kito\git\sources\dependencies\ogre_src_v1-7-4\OgreMain\src\OgreDynLib.cpp (line 91)
this is the closest I could find for you, what line of error is the end code? (the end number) Maybe I can find a way to fix it for you.
