I used HP recovery system on a failing (Vista) computer to backup all the data files before attempting to 'restore' the system. I backed them up onto a WD 'MyPassport' portable HARDDRIVE. I ended up installing Windows 7 on the machine to try and fix things up. Now I cannot retreive the backed up files back onto the machine. when I try to run the Backup.1 application stored in the folder where the files appear to be backed up, i get told that MSVCR71.DLL is missing and the APP cannot be run. I do not know how to get this dll into my machine. When I open the WD Smartware, it can see that the backed up files exist on the portable HD but it cannot open them or copy them to anywhere else.What exact app was this backup created with ? ?The machine I backed-up from had HP Assist and I beleive that the 'system recovery' options it OFFERED me MAY also have been HP proprietry. Prior to loading Windows 7 over the top of the old OS on this machine, I did retreive files from the backup to the machine. But I cannot retreive files to this or any other machine  now.
