Hi, I posted earlier about Sketchup and InstallShield and thanks to the help I got from this excellent list, that problem seems to be resolved. However, I am starting a new thread because the problem is now about actually running the program and specifically GL. This is the error I get: Unable to initialize OpenGL. Check drivers etc. and Error: ChoosePixelFormat failed I am running 20041091, an nVidia based system and OpenGL runs fine under Linux. I've googled and can't find a similar problem, so any pointers would be most appreciated.
