PowerShell Activity - "Requested registry access is not allowed" error RRS feed

  • Question

  • Hello all,

    Sometime the PS activity fire the below error, and I'm not able to figure it out why! Form the activity I'm calling Start-Process 'PowerShell.exe' -Version 3.0 -NonInteractive -OutputFormat Text -file (script path that runs PowerShell 3.0 cmdlets) - Any idea what would be the issue?

  • Confused by "sometimes". If it happens, it should always happen with this script. Probably has to do with ExecutionPolicy or the external script is blocked for execution.

  • Did you find a solution for this issue? I am seeing exactly the same when trying to run an AD PS cmdlet as per the documentation here: https://github.com/Microsoft/MIMWAL/wiki/Run-PowerShell-Script-Activity
