I’ve been having issues opening Horizon, when I start it the logo appears, but quickly disappears! I’ve tried everything including reinstalling it, restarting my computer, running as Admin, and disabling Firewall and my Anti-virus software. Please help!
Disconnect from the internet and see if that changes anything. If it does there are a couple possibilities, 1) your AV could be blocking it once it attempts to connect to the server 2) Your PC is banned from Horizon
2 is very unlikely unless you have used a cracked version
Turning off my internet seemed to do the trick, can’t believe that I didn’t think of that. Thanks!
omg i reset my damn internet and it worked 
and now once its connected to the internet it doesnt work again
