SCCM install error 0x1(1), -ExecutionPolicy Bypass has been specified

Question

Dear Experts,

I'm deploying an application via SCCM and specified

"%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe" -ExecutionPolicy Bypass -Command ".\Wim_Installation_Cleanup.ps1"

However In Software Center when trying to install the app, it showed 0x1(1) and in logs it also said Unmatched exit code (1) is considered an execution failure.

I referred to https://www.prajwaldesai.com/microsoft-edge-deployment-error-unmatched-exit-code-1/ and changed -Command to -File "Wim_Installation_Cleanup.ps1"
That didn't make any difference.

Please help.
Thanks a lot!

Answer 1

Do you have an execution policy assigned and enforced via policy (Intune or Group Policy)? If so, you can't override this locally.

Also, even if you don't, bypassing the execution policy is a terrible idea and practice. All PowerShell scripts should be signed and you should absolutely be enforcing the All Signed execution policy as well as PowerShell constrained mode.

Answer 2

Did you test your script using the local system account? https://www.recastsoftware.com/resources/how-to-access-the-local-system-account/
