I bought Windows 7 SP1 from PC Destination yesterday. My intent was to install it onto a clean hard drive partition. When I attempted to install the program, not only did it stop about 10% into the process, stating that it couldn't find a necessary driver, but the product was an upgrade and wouldn't install onto a clean hard drive at all. I feel as if I spent $40 on vapor ware that was not as advertised. Did I do something wrong?
