Installer displayed incorrectly ▾

In certain cases the installer may appear 'broken' and it will be displayed incorrectly. 

If that happens, please contact us.

Installer showing a "Connection Error" ▾

This issue is commonly caused by the following:

  • An anti-virus/firewall/VPN that might block the communication with the Overwolf servers
    Make sure to white-list Overwolf.
  • Corrupted machine.config file
    Please follow these steps to repair it:
    1. Go to C:\Windows\Microsoft.NET\Framework\
      1. Open the 'v2.0.50727' folder then 'config'
      2. Override 'machine.config' with 'machine.config.default' (delete the 'machine.config' file, duplicate the 'machine.config.default' file and rename it to 'machine.config') 
      3. Open the 'v4.0.30319' folder then 'config'
      4. Override 'machine.config' with 'machine.config.default' (delete the 'machine.config' file, duplicate the 'machine.config.default' file and rename it to 'machine.config')
    2. Go to C:\Windows\Microsoft.NET\Framework64\ and repeat steps a-d

  • Overwolf server malfunction or downtime
    Please try again after a while, just to make sure it's not a temporary issue.
  • Weak/Unstable Wi-Fi connection that disconnects every now and then
    Connect your internet via cable or make sure your Wi-Fi connection is stable.
  • The connection is blocked by your ISP (internet service provider)
    Reach out to your ISP to find out how to remove the block.

Installer not starting / finishing properly ▾

Overwolf is based on .NET Framework, and at times, the installed .NET component in your system may malfunction and prevent the Overwolf installer from running properly.

First, please make sure that the basic .NET Framework 3.5 feature is installed and enabled:

  1. Open the system's Control Panel
  2. Select "Programs" or "Programs and Features" (depending on the view setting):

  3. Select "Turn Windows features on or off":

  4. Make sure that the checkbox for ".NET Framework 3.5 (includes .NET 2.0 and 3.0)" is ticked. If there is an additional .NET Framework version in the list, as seen in the screenshot below, make sure that it is ticked as well:

    5. Restart your system (if asked to) and try to launch the Overwolf installer again.

If the .NET Framework 3.5 feature is already enabled, you may going to need reinstall the higher .NET Framework version (4.8) installed on your system. For more information, please visit this article.

Overwolf setup installer ▾

If the above-mentioned solutions did not help you overcome the issue, please try to run the setup installer.
It comes in a zipped file, so you will first need to extract it by using any program like WinZip, WinRAR or 7-Zip.
Once the installation is complete you can go ahead and start downloading awesome apps for your games!

Clean reinstall Overwolf client ▾

If all of the above does not work, and you are still unable to install Overwolf, then try doing a full clean sweep of all Overwolf files, then try to re-install it.

To uninstall Overwolf just go to: Start -> Control Panel -> Uninstall a Program and uninstall Overwolf.

Once you finish uninstalling, head to C:\Program Files (x86) and check if you have an Overwolf folder (you shouldn't). Delete it, and proceed to do the following:

  1. Press the Windows key + R
  2. Type: %localappdata%
  3. Press enter
  4. Look for a folder named 'Overwolf'
  5. Delete it

Once you finish, please re-download (choose your favorite app) and launch Overwolf.

Installation file is getting removed ▾

If the installation file is finished downloading but it's missing from your 'Downloads' folder, it usually means an antivirus or a download manager software are automatically deleting it. When clicking the file to run it, you may notice that the browser's download bar or page says the file is either 'Removed' or 'Failed - Download error'. For example:

We've seen this happen to users who have SAntivirus/Segurazo installed (sometimes, without even their knowledge), but it might also happen with other software. To resolve the issue you can temporarily disable the antivirus software and redownload the installer. For more information, please visit this article.

RivaTuner conflict ▾

RivaTuner Statistics Server is a hardware monitoring program that usually comes bundled with MSI Afterburner. Sometimes, it may conflict with Overwolf and prevent it from running properly (or running at all). 

To prevent any such issues, please follow the suggestions in our Overwolf and Conflicts with RivaTuner article, or close RivaTuner entirely for the duration of the installation (you may need to close MSI Afterburner first).
