[chimerax-users] ChimeraX not starting up using win10

[Greg Couch]

Hi bernd,

So I'm surprised that Chimera worked and ChimeraX didn't.  Before this, 
I've only seen it the other way around.  And it makes sense that 
installing python didn't help, because ChimeraX uses its own embedded 
copy.  From the python traceback, it looks like it is hanging when it 
tries to start up the user interface toolkit.  It is normal for ChimeraX 
to start up slowly the very first time, so I assume you waited a several 
minutes.  The delays are caused by your anti-virus software and by the 
initial runtime linking.

If waiting longer for ChimeraX to start doesn't work, then to debug 
this, please run the Windows "Event Viewer" application (you will need 
administrative privileges).  Then start up ChimeraX and look for recent 
events that are related.  If you don't see any events right away, then 
wait for ChimeraX to completely fail on its own, and then looks at the 
events.  And please share with me what you find.

     HTH,

     Greg
