[chimerax-users] ChimeraX not starting up using win10

[Bernd M. Schmidt]

Dear ChimeraX users and coders,

Thanks for the hard work and for providing the community with such great 
program.

I cannot run Chimera on my desktop PC. After clicking in win10, the 
cursor indicates something is happening for three seconds, then nothing 
happens and also no error message or anything appeares Before that, I 
ran Chimera 1.14rc successfully, since installation of ChimeraX and also 
with ChimeraX 1.2, this happens. I deinstalled everything and installed 
first the latest python release (3.9.5), then ChimeraX 1.2. But no 
change, nothing. Reading the newsgroup suggested running debug mode, 
finally giving some error message, as seen below.

C:\Program Files\ChimeraX
