I’m running Win10Pro (x64) and recently installed the update to 5.3.9. During the reboot, Micro$oft decided to install Windows Defender which caused my usual AV (AVG free) to stop working. After killing Defender and reinstalling AVG, I noticed that the tray icon for NX was not there. I tried running NoMachine Service and starting it up, but I was never able to see the server from my client machine. After snooping around the forums, I decided to see what Process Explorer could show me. Normally I see nxservice64.exe running, and sometime nxplayer.bin. When I launch NoMachine Service, I can see nxserver.exe with children conhost.exe and nxserver.bin start and very quickly shutdown. This continues about once/second until I shutdown NoMachine Service. I looked at the log files, but am a bit overwhelmed by the plethora of errors and need some expert guidance on where to go next.
