I've been trying to resolve the issue myself for most of the day by looking for answers on the internet, but found very little information. the only help i got was to clean my registry. but that didn't resolve the issue.
I'm running on Windows 8
Graphics Card: HD 7970 Black edition
Processor: Intel Core I5 2500k
Ram: 8Gb Corsair Vengeance
It's looks like i may have finally got it to work. by partially installing the game i found that by trying to launch it, take you to Uplay software, and then allows you to unlock it on your account. and i'm now trying to install it digitally.
Ubisoft really need to put in a feature like steam, where by you can put in the CD-key of the game and download it, instead of trying to install it from the disk. that would have made matters so much easier, especially considering i don't usually have my CD drive plugged in these days, as it never get's used. this has to be the first physical copy of a game i've bought in years, but only because it's not available on steam.
