Why are my PowerShell scripts not running?

Question

I wrote a simple batch file as a PowerShell script, and I am getting errors when they run.

It\'s in a scripts directory in my path. This is the error I get:

Answer 1

I was able to bypass this error by invoking PowerShell like this:

powershell -executionpolicy bypass -File .\MYSCRIPT.ps1

That is, I added the -executionpolicy bypass to the way I invoked the script.

This worked on Windows 7 Service Pack 1. I am new to PowerShell, so there could be caveats to doing that that I am not aware of.

[Edit 2017-06-26] I have continued to use this technique on other systems including Windows 10 and Windows 2012 R2 without issue.

Here is what I am using now. This keeps me from accidentally running the script by clicking on it. When I run it in the scheduler I add one argument: "scheduler" and that bypasses the prompt.

This also pauses the window at the end so I can see the output of PowerShell.

if NOT "%1" == "scheduler" (
   @echo looks like you started the script by clicking on it.
   @echo press space to continue or control C to exit.
   pause
)

C:
cd \Scripts

powershell -executionpolicy bypass -File .\rundps.ps1

set psexitcode=%errorlevel%

if NOT "%1" == "scheduler" (
   @echo Powershell finished.  Press space to exit.
   pause
)

exit /b %psexitcode%
