SC binary terminate just after HOST is clicked

Post by lazna »

Trying to set-up scheme:

SC - NAT - repeater - NAT - Viewer

Just create SC binary, start it, but when only listed HOST is doubleclicked, binary silently terminated. What could be wrong?

Windows 10/64bit
version of repeater: 1400
SC binary created by 2018 creator
Captured debug messages:
