What i do?
(Sorry for my bad english)

Try this. Uninstall Horizon if it actually installed, and delete the setup installer that you downloaded earlier. Now download Horizon from the link below and see if it installs and opens without any errors.

If you still have issues reply back and try to give us more info about what exactly is happening. Good luck.

It worked, thanks!

Horizon wont open, the logo comes up on the screen then nothing happens?

Antivirus or fire is why
