While the software could do a better job of detailing the problem, the answer is easily found all over the web by simply searching for those keywords on Google.

Note that you might get “Unable to open MSDM table!” message if the product key isn’t present in your PC’s BIOS/EFI. If you’re getting this message, the product key sticker must be located somewhere on your PC. Look for it!
