Just wanted to say thanks for this cool little tool, unfortunately for some odd reason after I install it and try to run it, it will not load. I repaired .NET framework, uninstalled and reinstalled Horizon, nothing.
Any ideas on what could be causing this? Thank You.
Hello and welcome to the community. 
Add Horizon as an exception in your antivirus. Usually the reason for software failing to launch is because antivirus software has interfered with it.
It’s probably best to remove Horizon completely then reinstall it with your antivirus turned off, then add it an an exception. In case a critical file has also been deleted by the antivirus.
Also, if you use Windows Defender, update your signature library. Here’s how: https://support.microsoft.com/en-gb/help/4027712/windows-10-update-windows-security-signatures
