I have a machine in for repair which is unable to install Vista SP1 or SP2, due to a previous malware infection. I'm reduced to trying to perform an in-place upgrade to try and repair whatever system files are damaged, but the only media I have available have SP1 or SP2 integrated, and they refuse to perform the install. Googling for the hash of the MSDN download hasn't produced any luck. Anyone able to help me out?
