I would close and restart steam. We haven't had anyone else have that issue

Already tried, the problem remains :(

let me double check with some people for you

When you restart steam and go to library - can you double check that you are not on the beta branch of the game? That is one thing that we are thinking

No, they are neither in the game beta nor in the Steam client beta

Where about are you located in the world? Just so we can see if this is a localized issue or not

Also I would try to exit steam and retry again

We would also suggest this thread

Same issue here. I'm on the US east coast. Only downloaded 37mb then says it's installed. But I get the "missing BrewmasterMain.exe" error when I try to start the game. No AV or VPN software running. Restarted Steam. Running verification of local files shows no issues. Didn't play Alpha or demo and not on Beta branch. Nothing in that thread Matty linked works or is relevant in my case. All my other games are playing and updating just fine.

Same issue here.
I am from Hungary.

I have the same issue. I am in the midwest U.S. I checked the game folder and it only shows save folder. Restarted steam, cleared download cache, repaired library folder, restarted computer, uninstalled and reinstalled, installed to different drives, installed to different computers, verified file integrity...nothing works.

We have just had a check on our back ends, if you close and restart steam it should be working fine now

I am back from work and now it works!
