Hello, I recently upgraded to a new workstation, and am running into trouble with installing Chimera. The error (with an exit code of 2) I'm getting is: Error initializing OpenGL: couldn't set pixel format Couldn't configure togl widget My workstation is 64 bit, running Windows 7, with a NVIDIA Quadro M4000 graphics card. I've tried installing the latest NVIDIA driver, which didn't seem to help. I've reinstalled Chimera several times, trying both 32 and 64 bit. My tech support also tried changing permissions on various files, to no avail. The weird thing is that my tech support folks got Chimera to open a few times successfully when they were logged in, which makes me wonder whether it might be a permissions issue, but they aren't able to get it to open consistently, either. Any ideas/advice would be welcome! thank you! Janet Iwasa
