Arma 3 launcher won't start.
Closed, ResolvedPublic


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!

there's an issue with automatic repair of corrupted user settings. Corrupted user settings is not detected correctly and the application the continue to run and crash because of it.

Try to run following hotfix, it will remove corrupted settings:
