What OS?

OS: Windows 7 (Service Pack 1)
AV: AVG 2011

yeah it won’t work with Service pack 1 :[ Now I can’t use Diamond or Horizon Beta, I pretty much wasted my last month because of the service pack. When will Horizon update?

SP1 doesn’t support Horizon, for now anyways.

For a lot of people it will work with the service pack, just run it in compatibility mode for Vista or XP. And make sure to run it as an administrator.

Otherwise this will be fixed for sure in the next update.

Cheater said it will be supported again in future updates.

Next update will bring support for SP1. Until then you can try running in compatible mode, but its not likely to work.
No ETA on the Horizon update either.

If you want to, you can uninstall the service pack, follow the instruction below.

Unfortunately, Horizon does not support Service Pack 1. There will be a future update correcting the problem. Until then, I suggest looking for tutorials on how to mod what you would like. If you need any help, just message me on AIM. My AIM is God.ly

I’ve tried all compatibility modes and none of them worked! when they release a new version of Horizon corrected? thanks for the help did not work more!
