Steps to Fix War Thunder Error Code 30005

1. Close War Thunder and Launcher

The first step is to completely close out of both the War Thunder game and launcher if they are currently open on your computer. This releases any processes or connections that could interfere with verifying and repairing the files.

2. Navigate to Game Directory

You’ll need to access your War Thunder game files directory on your computer. The default location for this game directory is:

C:\Program Files\War Thunder

However, if you did a custom install, your game directory may be in a different location.

3. Run Integrity Check

In your War Thunder game directory, look for a file called launcher.exe and double-click it to open the launcher. Even if the game is having issues running, this launcher should open.

Once the launcher opens, click on the wrench icon in the top right corner and select “Check files integrity.”

This will begin scanning your game files and checking for any corrupted, missing, or altered files. Let this integrity check process complete fully.

4. Repair Files

After the integrity check finishes, you’ll get a report of any files flagged as damaged or missing. Click the “Repair” button to restore any corrupted files or re-download any missing game data.

This repair and download process may take some time depending on your internet speed and how much needs to be repaired. Be patient and let it fully complete.

5. Restart Your Computer

Once the repair process finishes, close out of the game launcher and restart your computer. This will clear out any legacy processes or connections from the previous launch attempts.

6. Launch War Thunder Again

After your computer restarts, launch the War Thunder game again through the launcher. The error code 30005 should now be resolved, and you should be able to get into the game.

If the game still fails to launch or you receive the same error, you may need to repeat the integrity check and repair process. Also, double-check that your computer meets the minimum system requirements for running War Thunder properly.
