I can't test on windows server 2012, but from what I'm reading it might be a problem with x32 architecture. The builds so far were x64 only. I've made a test build for x32 windows. Let me know if that works: https://file.io/5oGY88k7rohp
As for zabbix, I've never worked with it. Maybe if someone made a PR for it. Right now I can't estimate how complex that would even be.
