I got "Server Connection Error" while installing Overwolf, what can cause this?

  • An anti-virus/firewall that might block the communication with the Overwolf servers.
    Make sure to white-list Overwolf.
  • 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.


Installer not starting\finishing properly

Overwolf is based on .NET 4.5. It's possible that .NET 4.5 wasn't installed properly on your PC.

In this case, Overwolf won't be able to run due to some corrupted files. Please make sure to go over this article.
