When running PowerShell script to restart a service via PRTG, you encounter the error: "Error sending 'EXE': File 'Powershell.exe' not found." PowerShell 3.0 is installed on the PRTG server. Do I also need to install PowerShell 3.0 on affected servers ?

If you have installed PS3 recently and didn't restarted your PRTG box the path variable to the powershell folder may not be set correctly.

Please try to run Powershell.exe from the DOS command line. If it's not found restart your PRTG box, and try again.

You can check the Path variable by 

set | grep Path

The problem may occur by 32/64 bit mix ups Please check if you PowerShell installation matches your PRTG installation.
