I just tried last night’s ChimeraX build on a new Windows 7 account and it started fine. Possibly your graphics driver is not adequate (requires OpenGL 3.3 core profile support or higher) — ideally it should show a warning dialog if that happened, but I have not tested that situation. Can you run ChimeraX from a command prompt with the —debug flag and send the output to chimerax-bugs@cgl.ucsf.edu?

Hi Hernando,

This was a bug in ChimeraX, probably recently introduced where it fails the first time you try to start it because its toolshed cache file does not exist. I’ve fixed it — in tonight’s build if it succeeds. Thanks for reporting the problem.

Dear ChimeraX team,

I just downloaded/installed ChimeraX (64 for windows, latest daily build & PC running Windows 7) but when starting the programs hangs with the message Initializing Core and an image of the group (Nice picture though!). Anything I should do differently? (Chimera 11.2 runs fine in the same computer).

Thanks

Hernando
