Why Won’t Terraria Launch?

The Terraria game didn’t go well with the launch because there are a bunch of bugs and connectivity errors appearing to the players no matter which gaming platform they’re using. So, it’s worth mentioning that Terraria is full of issues that we can’t deny, but sometimes the problems at your end or even with your PC (directly or indirectly) can trigger multiple game launching or crashing issues. So, without further ado, let’s get into it.

Your Terraria game may not launch due to an outdated game patch, an outdated graphics driver version or Windows build, missing or corrupted game files, issues with the Microsoft Visual C++ Redistributable, unnecessary background running tasks, etc. Whereas some players can encounter won’t launching of the game issues due to incompatible PC hardware, unnecessary background running tasks, overlay apps, and more.

If you’re not running your video game using an administrator privilege, it may cause issues with the game launching or startup crashing, or even the game not loading, etc. So, it’s better to simply run the game exe file as an administrator on your Windows computer to check if that fixes the problem or not.

Click on the Run this program as an administrator checkbox to checkmark it.
Click on Apply and select OK to save changes.

Right-click on Terraria from the list of installed games.
Now, click on Properties > Go to Local Files.
Click on Verify Integrity of Game Files.
You’ll have to wait for the process until it gets completed.
Once done, just restart your computer.

- 2012\vc_redist.x64.exe
- 2013\vc_redist.x64.exe
- 2019\vc_redist.x64.exe
Just make sure to run all of these executable files that are present. (If you’ve different folders, then run the vc_redist.x64.exe file in those folders)

According to some affected players, disabling the overlay apps such as Xbox, Discord, or any other on the Windows computer has helped them easily fix the game not launching issue. As the in-game overlay app is always running in the background whenever you launch the game client, it’s possible to have issues with the processes or system resources.

8. Install All Pending Windows Updates

From the left pane, click on Turn Windows Firewall on or off.
Select Turn off Windows Firewall for the Private, Domain, and Public Network Settings.
Finally, reboot the PC to apply changes and try checking the issue.

Now, you’ll have to disable the anti-virus protection (Windows Defender) as well by following the steps below:

Head over to the Windows Settings > Privacy and Security.
Now, go to Windows Security > Virus & threat protection.

In the General section, click on Set Launch Options.

 -windowed -noborder
