Hi. I've been using HDM 11 Suite with NO problems on my Lenovo V570 laptop with a Win 7 Pro 32 bit OS. I just got another V570 with a Win 7 Home Premium 64 bit system, and last night did a full system image backup. Tonight I went to do a differential system image backup to cover some changes that I'd made and even though there's a .PBF file clearly visible in the Browse For Archive window, when I click next, it says that the Wizard didn't find any objects that can be used for the differential backup. That's never happened before. So vaguely I think I remember having to choose between the 32 bit and the 64 bit downloads, but I'm not sure. I was able to use the partitioning parts of HDM 11 Suite without any problems to shrink and create new partitions. It's just the backup that's causing problems. Any help would definitely be appreciated.
