I have Among us v2020.12.5 under windows 10. I want to install the Sherriff mod, but I have no steam/steamapps folder anywhere on the machine. The docs and screenshots say it should be in my programs (x86), but it absolutely isn't. What is going on?
Go to your library on Steam, then right click Among Us. Go to Properties > Local Files. Click on Browse. It will open the folder where Among Us is installed, anywhere it is.
Steam/Steamapps is the usual place where Steam installs games, but if you switched the configuration it could be anywhere.
If you bought the game via the Microsoft Store, your files are still there, just behind some Microsoft BS.
Your Store downloads are in a hidden folder in Program Files > WindowsApps.
Open File Explorer and click on the Program Files folder. Click on the View tab. Check the box next to Hidden items.
In fact, maybe you could make it work by right clicking the shortcut on the desktop, go to Properties, and the location might be in the Target field. Then copy the whole URL (Starting by a capital letter like C or E) until the last / before the .exe file, and paste that in Run. (Open the start menu, type run then enter). It should open the folder.
