Check whether you batch / commands work when running in the LocalSystem account (like BESClient does) using psexec

Bigfix action executed but no result in windows machine

The easiest way to test programs running as LocalSystem is with psexec from https://microsoft.com/sysinternals With that, you can run psexec -i -S cmd to open a command shell as the LocalSystem account, and then try executing your powershell.
