Disable your Anti-Virus, that’s the main cause.
If you have Avast! Anti-Virus, disable it but following this tutorial:
[details=Open Me]First off, you want to go down to the lower Right-Hand corner of your screen. It should look some-what like this;
Right-Click the Avast! icon. The icon should look like this;
Once Right-Clicked, something should pop up like this;
Click on “avast! shields control”. Something then should pop up looking like this;
When you are there, you can click on the time(s) you want to disable your firewall/anti-virus so you can run Horizon.
Once you have clicked that, you should be prompted to disable it. It should look like this;
Just click “yes”, then you can run Horizon. 
You can keep Avast! but always do this to ensure that Horizon will work with-out getting an error on start up.[/details]
You may also want to try disabling Windows Firewall:
Open Windows Firewall by clicking the Start button 
, clicking Control Panel, clicking Security, and then clicking Windows Firewall.
Click Turn Windows Firewall on or off
. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Click Off, and then click OK.
Check your anti-virus firewall, it could be blocking Horizon from accessing the server.
I’m getting the same problem. The thing is, I disable the firewall and it still doesn’t work. I have McAfee, not Avast!. I don’t know what to do…
