Same exact problem here. 4 times I've installed it...downloaded it and i'm stuck in the loop where it downloads it over and over. Same issue where Antivirus is blocking it as well!??!! SOOO Frustrating!!!!

Exact same issue with a Radeon 7970. I have become so frustrated that I've gone back to using Unity with the DK1 with the demo i've been working on. I hope it will convert ok to the DK2 when they figure out this stuff.
