Will not launch!

when i try to launch horizon it brings up the “horizon” text on my screen then disappears without actually opening the modding tool… :confused:

Do you know if you have .Net Framework 3.5 installed?
If you don’t, get it here: https://www.microsoft.com/en-us/download/details.aspx?id=21

You should also try a fresh install of Horizon after uninstalling your current version, and then reinstalling after downloading the latest version from here: https://www.horizonmb.com/client/v2/latest.php

I actually have the same problem as of recently, I open up Horizon under regular and Admin privileges, all it does is load the Horizon logo and kills the process. I have reinstalled multiple times, deleted it from the localappdata folder, cleaned up and reinstalled my Net Framework to no avail. The only thing that comes to mind is a few days ago I was playing Borderlands The PreSequel on Steam and I caused an error that made it impossible to play it or Borderlands 2 -yet every other steam game worked flawlessly- until I plugged in my 360 controller and it magically resolved itself. I highly doubt that it is related, but I’m at a loss at what else to try.

OS : Windows 8
Antivirus/Firewall : None
Errors : None
Extra Information : None… no errors or anything other than when watching the process in Task Manager, it loads up the .exe then it kills itself and vanishes
