I’ve just downloaded infinity & installed it. yet when I open infinity it won’t open. Any help? 
Horizon runs just fine and opens. It’s just infinity
Do you have .NET Framework 4.6 installed? I believe Infinity installs it during its install but you might want to try directly installing it from here: https://www.microsoft.com/en-us/download/details.aspx?id=48130
I believe I do, and infinity installs fine. It’s just when I open infinity nothing happens. (I’ve tried opening It with task manager as well.)
