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