Hi Yuekan,

That makes me wonder whether the condition is intermittent on your system
-- i.e., sometimes it works, and sometimes it doesn't, apparently randomly.

I say that because fiji-win64.exe is AFAIK just a thin wrapper which
invokes ImageJ-win64.exe. You could verify that for yourself by running the
"System information" command (use Ctrl+L to find it via the Command Finder)
in both cases, save the output (Ctrl+A Ctrl+C to copy it, then paste into a
text editor), and diff the two against each other. I would be surprised if
the environments are meaningfully different.

Regards,
Curtis
