Cannot load custom powershell module

Hello friendly folks,

I started building a script using NetCmdlets (https://www.nsoftware.com/powershell/netcmdlets/download.aspx) for the EXE/Advanced sensor for monitoring a NetScaler with snmp. But the logging of a simple script says it cannot execute the custom commands (e.g. Get-SNMP). When I explicitly try to load the module it says it cannot be found. Using paths, names, full path, module or data file loading, the error keeps coming when I do a Scan Now.

I assume it has something to do with the usercontext under which PRTG executes the script that it cannot find the module (despite it being in the default win\sys32\ps\1.0 etc. path). Any ideas on this issue? PRTG runs under the Local System user.

Thanks in advance!
