Workflow does not start when PowerShell Script is run from Task Scheduler

Incorrect configuration may cause this.

Try following.

1. Run powershell script using a batch file.

powershell .\scriptname.ps1

2.

make sure following configuration.

Action Start Program

C:\Scripts\scriptname.bat

Start in C:\Scripts\

Select "run whether user logged in or not."

Sometime you may be running higher version of powershell that may also be issue. i faced this issues when i were trying to run powershell for sharepoint 2010 on Windows server 2012.

So you can use following command in batch file.

powershell -version 2 .\scriptname.ps1
