ChimeraX 1.3 won't start (Windows 10)

[sitb@…]

?Hi,

I am encountering an issue where my XPS15 Windows 10 x64 laptop will not start ChimeraX1.3. I previously was successfully using version 1.2.5. as recently as a couple of days ago, but starting running into this issue today where I try to run the program and nothing happens (no dialog/windows). If I try to run ChimeraX by opening a PDB file, I have the same issue, but a ChimeraX application window will open for a couple of seconds before closing. To troubleshoot, I uninstalled 1.2.5 and installed the stable 1.3 build, and also updated my OS and restarted my computer. However, I am still having the same problem - any assistance would be appreciated.


Thanks,

Brandon Sit

The most common reason ChimeraX fails to start is your system graphics driver updated and is broken now. The fix is to install a working graphics driver (either a newer version or older version).

Another rare possibility is that the saved ChimeraX preferences got corrupted somehow. These are saved in directory

C:\Users\your-user-name\AppData\Local\UCSF\ChimeraX

and you could just rename that directory so that ChimeraX creates a new one to see if that is the problem.

One last thing you could try to see if there is an error message is to start ChimeraX in debug mode by right clicking the desktop icon, choose Properties, and change Target from

"C:\Program Files\ChimeraX 1.3\bin\ChimeraX.exe"

to

"C:\Program Files\ChimeraX 1.3\bin\ChimeraX-console.exe" --debug

Then when you double click that icon it will bring up a console that logs ChimeraX messages as it starts up and you may see an error that explains what went wrong.
