    Hi all,

    I am trouble shooting a few issues with my system and these two errors are popping up continuously. Any ideas how to resolve?

    Event ID 8193

    Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance. hr = 0x80040154, Class not registered
    .

    Operation:
    Instantiating VSS server

    Event ID 22

    Volume Shadow Copy Service error: A critical component required by the Volume Shadow Copy service is not registered. This might happened if an error occurred during Windows setup or during installation of a Shadow Copy provider. The error returned from CoCreateInstance on class with CLSID {e579ab5f-1cc4-44b4-bed9-de0991ff0623} and Name IVssCoordinatorEx2 is [0x80040154, Class not registered
    ].

    Operation:
    Instantiating VSS server

    I am running Windows 7 Home Premium 64 bit on a self built machine.

    Thanks in advance!
