So it appears you are trying to run Chimera on Microsoft Windows. The warning about gzip is normal and should be ignored. The most likely cause of your error is that your graphics driver is out of date. So please update your graphics driver and try again. If it still doesn't work, then please use our online bug submission form, https://www.cgl.ucsf.edu/cgi-bin/chimera_bug_report_2.py, and attach the output from the dxdiag program (type dxdiag into the Windows search bar by the Start button, click on the dxdiag program it finds, then click on "Save All Information..." to save all of the information, and attach that file.) Good luck, Greg On 8/23/2021 10:51 AM, Pritam Dey via Chimera-users wrote:
