I have an AMD Radeon HD 6310 Graphics. I'm running windows 10. After I download the Catalyst 15.7.1 file windows scans it and says it is corrupted or invalid, so I can't install it. I've looked all over the net and AMD's site and tried to install other versions and found what appeared to be a newer one, but all were corrupted or invalid. The article I read that came with this update said it would be the final update for my system, so I would really like to be able to install it.
