So, I'll try to launch Arma 3 through Steam and it never actually launches, Arma 3 just immediately begins synching with steam again, the only reason I know it's a problem with the launcher is that I can go in to the Arma 3 folder and lauch arma3.exe and it works perfectly fine. I used the LauncherStructuralDiagnostics thing and I saved the report.

It says I'm missing some files but I verified the cache and it says everything is there, I tried reinstalling .NET with no results, I'm honestly clueless here and would appreciate any help I can get, thanks!
