sccm client not running powershell script on some machines

[jblackburn]

I'm getting an error back on around 20% of clients failing to run scripts.

When my script runs that is part of an advert I get an error in execmgr.log listing error

"Invalid executable file powershell"

The exact same script is working on 80% of machines!! I am currently on Windows 10 generally build 1703 but the issue happens on build 1709 as well. If I rebuild the machine I get no issues the scripts run on the same machine. I'm trying to figure out the cause so I don't need to reimage the whole machine just because it won't run a powershell script. My sccm is on the latest 1803 and the clients are updating correctly showing the latest version

I am using the following command to execute the script

powershell -executionPolicy unrestricted -noexit -file ".\filename"

Execmgr give the following as an example.

Have you looked at any of those computers and run the script as the local system to confirm the results. 

[jblackburn]

Yes I can run manually. I am opening powershell with admin rights, setting the executionpolicy to bypass then running the script. It works

If I get the sccm client to run the script I get the error. I was looking at permissions but I can't figure out a pattern.

[GarthMJ]

Did you run the script as the local system account on ones of these computers?
