Installing tModLoader

Go to the tModLoader download page. Scroll down until you see Download, and then click the operating system you use.

Save the .zip file to your desktop.

Open your Terraria folder. By default, its location is C:\ProgramFiles\Steam\Steamapps\common\Terraria. It is very important for you to create a copy of the Terraria.exe file.
