🌲Why is Terraria not launching?

Terraria is not launching due to corrupted game files, problems with Windows permissions, unnecessary background apps, missing Visual C++ dependencies or .NET framework, problems with the Firewall or antivirus blocking the game, compatibility issues with your version of Windows, or other game files issues.

🌳How do I fix Terraria launch error?

Start by applying the following checks and fixes:

  • Run Terraria as an administrator: Right-click on the Terraria executable (.exe) file, select Properties and navigate to the Compatibility tab. Enable this option and hit OK.
  • Temporarily disable antivirus: If the game launches, whitelist it in the antivirus settings and re-enable the antivirus protection.

Here are the best solutions to apply when Terraria isn’t launching.

  1. Install Visual C++ dependencies
  2. Allow Terraria through the Firewall
  3. Add launch options

1. Install Visual C++ dependencies

Games on Windows require Visual C++ dependencies to run. These are usually installed with the game or game distribution platform. However, if the installation didn’t happen or the dependencies are outdated, you must head to the official Microsoft website to download and install them.

  1. Open the official page for the Visual C++ Redist Packages download.
  2. Click on the Link and download vc_redist, which suits your operating system architecture.

Time needed: 5 minutes

  1. Click on the Windows icon, type Windows Defender Firewall, and open it.

  2. Click on Allow an app or feature through Windows Defender Firewall.
