I have the same problem too, any luck finding a fix ?
No... My friend installed it succesfully and he said they made a really good work. He gained 10 more FPS on Assassin's Creed Syndicate, so this is a right step for AMD.
I get the same problem. The installer freezes at 2% and you get a not responding. I got to 16% once, but it froze there too. Now it is 2% again, every time.
