I’m facing “Unable to download file” error

※What does the “Unable to download file” error mean?

This error usually appears during the Ragnarok Online client update through the patcher. It means the patcher failed to download or apply one of the necessary files to launch the game properly.

※What are the most common causes?

• Internet connection issues (instability or packet loss)

• Firewall or antivirus blocking the patcher

• Insufficient permissions to run the patcher

• Corrupted or incomplete game files

• The game or patcher is already running in the background

※How can I fix it?

Try the following steps:

1. Restart your computer and your internet connection

2. Run the patcher as Administrator: right-click the game icon and select “Run as administrator”

3. Temporarily disable your antivirus and firewall, then try updating the game again

4. Check if the game or patcher is already running in the background using Task Manager (Ctrl + Shift + Esc)

5. Reinstall the game: as a last resort, completely uninstall your current version and download a fresh, updated copy from the official site

※The issue persists. What should I do?

If the problem continues after trying all the steps above, we recommend contacting our Customer Service for further assistance. When submitting your ticket, make sure to include:

• A description of the error and when it happens (e.g., when launching the patcher, after a few seconds, etc.)

• A screenshot of the error message, if possible

• Your DxDiag report (system diagnostics)

• Information about the antivirus or firewall you’re using

How to get your DxDiag:

1. Press Windows + R on your keyboard.

2. Type dxdiag and press Enter.

3. Wait for the tool to load.

4. Click "Save All Information…" and save the file to your Desktop or another folder.

5. Attach this .txt file to your support ticket.

✱Extra tip:

Avoid renaming or moving the game folders manually after installation. If you're using an outdated or unofficial installer, this may cause patcher issues.
