I’ve been using Horizon ever since I got into modding games, and it has ALWAYS worked for me, Until now that is.
Every time I try to launch Horizon, I get a window that shows that Horizon has stopped working.
This has only started happening recently and I have no clue why it’s happening or how to fix it.
Any help would be appreciated!

Try downloading .Net Framework 3.5 from the link below.
Download .Net Framework 3.5
I did and Horizon still refuses to open
Okay, so I decided to click the Horizon banner on your name and it gave me a new version, which I downloaded, and it opened.
So thank you!
