How to Fix Paradox Launcher Not Working Issue?

Paradox launcher users frequently encounter issues when attempting to start games published by Paradox Interactive. You may face various problems with the Paradox launcher, such as it freezing or presenting error messages during game launches.

Several factors can cause the Paradox launcher to malfunction. Occasionally, third-party antivirus software—particularly Avast antivirus—interferes with the background operation of the Paradox launcher’s executable files.

Additionally, interference from other third-party applications and corrupted launcher files can result in its unresponsiveness.

1. Add Exception for Paradox Launcher in your Antivirus

When you add an exception for the Paradox Launcher in your antivirus, you’re instructing the software to trust the application. It’s important to note that this is a common and safe procedure for resolving conflicts between gaming launchers and antivirus programs.

The Paradox Launcher is a legitimate piece of software from a reputable gaming company, Paradox Interactive. However, you should only download the launcher from official or trusted sources to ensure its integrity.

  1. Launch your antivirus software, access the Menu at the top, and select Settings.
  2. From the side menu, choose Exceptions and then click Add Exception.
  3. Select Browse and navigate to the Paradox launcher directory to add the executable file.
    C:/Users/UserName/AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.10.1

    Note: Replace “UserName” with your actual Windows username—the one you use to log into your computer. If you’re not sure of your username, it can be found in the C:/Users directory.

  4. After adding the exception, check to see if the issue has been resolved.

2. Clear the Application Data

Corrupted application data, like user settings and cache files, can lead to these launcher issues. Clearing the application data ensures there are no corrupted files causing problems.

  1. Right-click the Start Menu and pick Run from the options.
  2. In the Run dialog, type %appdata% and click OK to proceed.
  3. Navigate to the Local folder and remove the Paradox Interactive folder.
  4. Try launching the Paradox launcher again and see if the problem persists.

3. Perform a Clean Boot

Executing a clean boot can help determine if third-party services or applications are causing interference with the launcher. In this mode, only essential services and programs will run at startup.

  1. Right-click the Start Menu and choose Run.
  2. Type msconfig in the dialog box and click OK.
  3. Select Services at the top, check Hide all Microsoft services, and then click Disable All.
  4. Restart your computer and check if the issue has been resolved.

4. Reinstall the Paradox Launcher

If none of the above solutions work, consider a clean reinstallation of the Paradox launcher. This could resolve potential issues from corrupted files.

  1. Right-click the Start Menu and select Settings.
  2. Go to Apps > Installed Apps and find the Paradox Launcher.
  3. Click the three dots next to the Paradox Launcher and choose Uninstall.
  4. Confirm by clicking Uninstall again.
  5. After uninstalling, download and install the latest version of the Paradox launcher.

Should these approaches fail to resolve the issue, it’s advisable to reach out directly to the Paradox support team for further assistance.
