PowerShell says "execution of scripts is disabled on this system."

Question

I am trying to run a cmd file that calls a PowerShell script from cmd.exe, but I am getting this error:

Management_Install.ps1 cannot be loaded because the execution of scripts is disabled on this system.

I ran this command:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted

When I run Get-ExecutionPolicy from PowerShell, it returns Unrestricted.

PS C:\Users\Administrator\> Get-ExecutionPolicy
Unrestricted

The system is Windows Server 2008R2.

What am I doing wrong?

Answer 1

If you're using Windows Server 2008 R2 then there is an x64 and x86 version of PowerShell both of which have to have their execution policies set. Did you set the execution policy on both hosts?

As an Administrator, you can set the execution policy by typing this into your PowerShell window:

Set-ExecutionPolicy RemoteSigned

For more information, see Using the Set-ExecutionPolicy Cmdlet.

When you are done, you can set the policy back to its default value with:

Set-ExecutionPolicy Restricted
