Security programs may block communication with Overwolf’s servers.
Please whitelist Overwolf or temporarily disable the software during installation.

To repair it:

  1. Open: C:\Windows\Microsoft.NET\Framework\

  3. Replace machine.config with machine.config.default

    • Delete machine.config

  5. Then repeat the process in:
    C:\Windows\Microsoft.NET\Framework64\

3. Overwolf server downtime

This may be temporary. Try again after a short while.


4. Weak or unstable Wi-Fi

Connect using a wired connection or stabilize your Wi-Fi.


5. ISP (Internet Service Provider) blocking the connection

Contact your ISP to request removal of the block.


Installer not starting / finishing properly ▾

Overwolf relies on the .NET Framework, and sometimes the installed .NET components may malfunction, preventing the installer from running correctly.

First, check that .NET Framework 3.5 is enabled:

  1. Open Control Panel.

  2. Select Programs or Programs and Features.

  3. Click Turn Windows features on or off.

  4. Ensure .NET Framework 3.5 (includes .NET 2.0 and 3.0) is checked.

  5. If another .NET version appears in the list, make sure it is checked as well.

  6. Restart your system if prompted and try launching the installer again.

If .NET Framework 3.5 is already enabled, you may need to reinstall .NET Framework 4.8.
Instructions can be found in this article.

Overwolf setup installer ▾

If none of the solutions above help, try running 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!

Installation file is getting removed ▾

If the installer finishes downloading but disappears from your Downloads folder, an antivirus or download manager is likely deleting it automatically.

You may see “Removed” or “Failed – Download error” in your browser’s downloads list.

This issue is commonly caused by SAntivirus / Segurazo, but other programs may behave similarly.

Please temporarily disable your antivirus software and redownload the installer.
