I've been trying to download windows 7 pro 64 bit for the last few days. I purchased it from Digital River through the Microsoft website. Every time I attempt to download it, it get to about 68% and stops completely. It just so happens that 68% is 2044 MB or about 2 GB. I'm wondering if there's some kind of file size download limit or if it is Digital River's fault that I can't download it. I've tried it multiple times. I even reformatted my hard drive, thinking it was an issue on my end. Even after the reformat and restoring my machine to the original factory settings, the download still stops at exactly 68%. Can anyone offer an help?
