Have it downloaded 100 times but it’s simply not have windows 8 I do not know what the problem is whenever I try to install it it does not install one of you has a solution would be important and sry for my english 've only translated by google translator = \

Right click on the setup installer and click on properties, now find the Unblock button near the bottom and click it, and click Ok. Now try installing Horizon. If it still gives you problems delete the installer you have on your PC, and download it again from the link below and try again. Good luck.
