This application allows you to downgrade your game to any of the past game versions where the steam manifest IDs are known.
This application is NOT a pirate tool and requires users to already own the game.
Step 1) Make sure you have .NET 6.0 Runtime installed on your computer.
Step 2) Click the Settings tab and enter your Steam account name and password. This is used to download the game versions from steam.
Step 3) In the Downloader tab, select the version you want to download and click the download button in the bottom right corner.
Step 4) A command prompt window will appear. If your Steam account has 2-way verification, Enter your Steam Guard authentication code into the command prompt and hit enter.
Step 5) The game version will download to the TerrariaDepots folder. This Can be changed to any desired location in the settings tab!
Step 6) If the game does not start and you receive this error message, backup and paste depot files to your game directory. Then run via steam.
(Or check out the Overwrite Steam Directory feature)

Steam allows the downloading of previous game versions through the use of depots. Depots are a collection of files pertaining to a group; for steam, the game Terraria. When a game gets updated, steam archives each patch as something called a manifest ID. Using steam console and the correct manifest ID, you can downgrade/download any game version that you own on your account. Using an open source utility called DepotDownloader, you can download depots with a lot more flexibility.

Why this is happening?
Built into Windows 10, is something called Windows Defender SmartScreen. Each time an application is ran Windows 10, SmartScreen will check if it is a “good” application against their catalog of applications. It’s a good security measure and is particular helpful at stopping malware spreading through email attachments – where some users do not understand the difference between a legitimate document and an application. Sometimes SmartScreen will prevent applications you know are not bad – for example, it’s a CMD or VBS script you wrote, or a program from a trusted source.
