Hi I have just upgraded from Vista to Win 7 Premimum on a new Toshiba laptop with 1 disk drive partionioned into C;(system) and Data drive. When attemting to run MS backup i get a error message saying VSS has failed. In the Appliction log i get the following following 4 entries (in the order in which they occur):

Volume Shadow Copy Service information: The COM Server with CLSID {65ee1dba-8ff4-4a58-ac1c-3470ee2f376a} and name SW_PROV cannot be started. [0x8007007e, The specified module could not be found.
]

The backup was not successful. The error is: A Volume Shadow Copy Service component encountered an unexpected error. Check the Application event log for more information. (0x80042302).

This is driving me mad! Can any body advise a solution. I have tried a a repair install with no luck

Thanks
