    Actually that service was not started. But I have fixed my problem by following the instructions below from:

    Did you have PowerShell 1.0 on the same machine? if so Uninstall the following:

    1. Update for Microsoft Windows (KB971513)
    2. Update for Windows Internet Explorer (KB975364)
    3. Microsoft Base Smart Card Cryptographic Service
    4. Windows Powershell 1.0 MUI Pack
    5. Wndows Powershell 1.0
    6. Windows Management Framework Core

    Then reinstall PowerShell 2.0

  • I needed to run

    Problem was resolved by reseting the security - choose your own switches or use the following to drop a log file to the root of C: by typing the following in a command prompt:

    %windir%\system32\secedit.exe /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /log C:\secedit.log /verbose

    before I could fix this issue
