'Runtime newer' error when attempting to load WebServices DLL into PowerShell

    When attempting to load the ManagementConsole.WebServices.dll module into PowerShell an error message is received stating

    "Could not load file or assembly 'file:///C:\Program Files\AppSense\Management Center\Console\ManagementConsole.WebServices.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded."


    By default PowerShell uses the v2 .NET framework (as can be seen by executing $PSVersionTable and checking the CLRVersion) whilst the ManagementConsole.WebServices.dll requires the v4 .NET framework.

    To enable PowerShell to use the v4 .NET framework create a 'powershell.exe.config' file with the below content and copy to the following locations:

    • C:\Windows\System32\WindowsPowerShell\v1.0
    • C:\Windows\SysWOW64\WindowsPowerShell\v1.0 (if the machine is 64 bit)


    <?xml version="1.0"?>


        <startup useLegacyV2RuntimeActivationPolicy="true">

             <supportedRuntime version="v4.0.30319"/>       

             <supportedRuntime version="v2.0.50727"/>       




    Reopen the PowerShell process, check the CLRVersion loaded in PowerShell.exe is now v4, and the script succeeds.
