I purchased the $29.99 student edition of Windows 7 today. The download process seemed to work fine, and all the folders seemed to successfully download to my desktop (expandedSetup, setup1.box, setup2.box, and Win7-HP-Retail-en-us-x86). I opened the .exe and it started, however after about 20 seconds of "unloading the box" I receive an error stating, "an error was encountered. The file or directory is corrupt and unreadable." I'm not sure if I should delete and re-download the files. I'll be very grateful for any and all help received.
