“Backup mismatch” is refered to as the error you get when you reformat your PC and try to load up a previous backup that was created for the previous install of Windows you had installed. This error is extremely frustrating to those like me that legitimately just reformatted a partition (or created new partitions) and have the same operating system with the same key installed on the machine, or use OEM versions of Windows (that create their own keys). So far my attempts at getting WD Backup to recognize my backup have failed, but I am wondering if anybody has solved this problem before and has a solution? I suspect it involves RegEdit, and a couple of reboots and reinstalls of the software.
Tech support gave me the run around multiple times, I am pretty much done with them. Their answers were just as relevant as swiss cheese is to this post. I must have typed out the same response five times and got five different answers. It could be the WD Anywhere Backup Key, it could be my Windows Key (which the former OEM key is long gone, BTW). I suspect it goes by your WIndows Key in determining what computer you are using.
If any veteren could provide a workaround for this, it would be MUCH appreciated, since Tech support seems to want to pretend that my issue does not exist.
