An issue in which you are stuck in an ‘infinite’ loading loop when launching or trying to update the Nexon Launcher.

An issue where the Nexon Launcher will auto-close after attempting to load.

An issue where a Javascript Error Appears.

Close out of the Nexon Launcher.

Re-open the Nexon Launcher and an update should automatically start downloading.

If you’re still experiencing the issue, perform a full restart for your computer, then repeat step 3.

If you’re still experiencing the issue, repeat step 3 but run the Nexon Launcher as “Administrator”.

Once the download is finished, you’re good to go! Have fun in game!

If the infinite loading issue persists, please uninstall the Nexon Launcher completely, download it again and re-install it.

Uninstalling the Nexon Launcher will not impact games that have already been downloaded and installed.

The Nexon Launcher uses 5 different ‘TCP Ports’ to run the application on the computer. If the launcher program is running on another port, there may be a conflict. In order to determine if this may be the case for you, please follow below:

Open your Task Manager (Ctrl+Shift+Esc)

Redirect through the following menus: Task Manager > “Performance” tab > Open Resource Monitor > “Network” tab > “Listening ports” section.

Make sure your nexon_client.exe and nexon_runtime.exe applications are running on one of the following ports:

5311

5577

5575

7000

7001

If your client is not running under this port, please end the process by right clicking the process under the “Processes with Network Activity” tab on this page.

Re-open the Nexon Launcher and an update should start downloading automatically.
