I've not had any problems, but I just checked and troubleshooting log is enabled (is that the default?). I just turned it off on one computer to see if it crashes.
I have FARR with FCalc installed, under Win10 Pro, and experience no problems. Seems to work just fine.


and the troubleshooting log is disabled.



I want to use '=' to open fcalc so I entered this to "Regular Expression (custom override)":
^=(.*)$|^=$
It opens fcalc just fine, but when I hit enter fcalc disappears and the command line gets replaced with 'fc'. So I tried using this regex instead:
^=(.*)$|^=$|^fc (.*)$|^fc$
... which keeps fcalc opened, but it stops functioning (or at least stops reacting to me entering more expressions).
Thanks for any suggests-
FCalc is built on muparser; see the built-in functions here:

I guess you want atan()? This gives results in radians. You can get degrees with the built-in "_pi" constant like
fc atan(1)*180/_pi
