Download issues!

When I tried to download horizon for my family mac and did all the stuff it asked it ended up downloading two random things to my mac and just crashed the computer. help?

Horizon is only available for windows.

Ok I tried with windows 8 but it wont work on my windows either. it says “horizon-setup.exe couldn’t be downloaded” what do I do

This download should work for you:
Windows 8 should work completely fine but Mac won’t sorry.
