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

 

I am trying to run the a .cmd file that calls a PowerShell script from the command prompt, and I am getting the below error:

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

I have ran set-executionpolicy unrestricted and when I run get-executionpolicy from PowerShell I get unrestricted back.

//Output from Powershell

PS C:UsersAdministrator> get-executionpolicy

Unrestricted

//Output from DOS

C:ProjectsMicrosoft.Practices.ESBSourceSamplesManagement PortalInstallScr

ipts>powershell .Management_Install.ps1 1

    The system is Windows Server 2008 R2.

    What am I doing wrong?

    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.

    您可以通过在运行PowerShell时添加-ExecutionPolicy ByPass来绕过此策略

    powershell -ExecutionPolicy ByPass -File script.ps1

    I had a similar issue and noted that the default cmd on Windows Server 2012, was running the x64 one.

    For Windows 7 , Windows 8 , Windows Server 2008 R2 or Windows Server 2012 , run the following commands as Administrator :

    x86 (32 bit)
    Open C:WindowsSysWOW64cmd.exe
    Run the command powershell Set-ExecutionPolicy RemoteSigned

    x64 (64 bit)
    Open C:Windowssystem32cmd.exe
    Run the command powershell Set-ExecutionPolicy RemoteSigned

    You can check mode using

  • In CMD: echo %PROCESSOR_ARCHITECTURE%
  • In Powershell: [Environment]::Is64BitProcess
