When installing Overwolf or an Overwolf app, you may encounter one of the following issues:

1. The installation file finishes downloading but disappears from your Downloads folder

This usually means your antivirus or a download manager is automatically deleting it.
When you try to run the installer, your browser may show messages like “Removed” or “Failed – Download error.”
For example:


2. You run the file, approve the UAC (User Account Control) prompt… and then nothing happens

The installer never opens or continues.
