This is a graphics driver problem. Please upgrade your graphics driver to latest version available for your computer. If you have a laptop, get the graphics driver from your laptop vendor (unless you have a NVidia GeForce 7 Go or an ATI Mobility Radeon 9600 or newer). Otherwise, if you have a NVidia graphics card, get the latest driver -- likewise for ATI, 3DLabs, Intel, SiS, etc. Greg Couch UCSF Computer Graphics Lab On Mon, 30 Oct 2006, Mareike Goeritz wrote:

Hello,

I'm interested in using Chimera, but after downloading and installing the software I'm unable to launch the program. I always get the following error message: "Microsoft Visual C++ Runtime Library: Assertion failed! Program: C:\Program Files\Chimera\bin\pythonw.exe File: togl.c Line: 2994 Expression: res==TRUE For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts (Press Retry to debug the application - JIT must be enabled)"

I'm not familiar with C++, so I don't know what to do. Does anybody know what might be missing or what's the problem? Thank you for your help!!
