I've read many topics with the same problem, but have not found a solution. I'm trying to get SNMP from server on Windows 2012. Mib-file taken from %windir%/system32 and converted using Paessler MIB importer v3.4.6 alpha. Checked by Paessler SNMP Tester 5.0 (Beta 11) - works fine. But when you add the sensor SNMP Library - I get the error "No available interfaces on this device (code: PE049)"
Mib, oidlib and log files - https://www.dropbox.com/sh/6j8dhsslbbnziyo/ZKf3-3blF0
