PRTG Error PE181 but Powershell 2.0 is installed

I got an error on my probe server.

The Windows Update Status sensor reports an error on the probe server device:

Dieser Sensor benötigt die PowerShell 2.0 (oder höher) auf dem System mit der PRTG Probe.

(´╗┐<?xml version="1.0" encoding="utf-8"?> <prtg> <error>1</error> <text>Unable to cast object of type 'System.Management.Automation.PSCustomObject' to type 'System.Collections.ArrayList'.</text> </prtg>) (Code: PE181)

But I have Powershell 2.0 and 5.1 installed.

It already worked months until now.

Hi Simon,

Please issue the following command in a 32-Bit PowerShell:

$PSVersionTable.PSVersion

Please post the result of the command.

Best regards.

I am having the same problem here. I am pretty sure this started happening after the last update. I updated last Sunday!

Hi there,

Please note that the PowerShell version of the probe needs to be at least v3. Please issue the command again on the Probe Server in the 32Bit PowerShell:

$PSVersionTable.PSVersion


Best regards.

Hi, same Problem here....on the remote probe I get

$PSVersionTable.PSVersion

Major  Minor  Build  Revision
-----  -----  -----  --------
5      1      14393  1715

and now? Any Idea? It's a 2016 Server and WSUS Powershell Sensor ist not working to any Server.... If I connect via powershell to the other Server (from the remote probe..) with enter-pssession it is no problem to get the WSUS Status.

The error is actually different, please provide us with Probe Status Files via [email protected] so we can check what's going on :)


Kind regards,

Is this the actual (Remote) Probe where the Sensor resides on?
