  1. Check your Downloads folder, or search your computer for the Malwarebytes setup file, Note that "x.x.x.xxxx" is the version number.
  2. Open the setup file by double clicking on it. If you can't open the file because it's from an unidentified developer, right click on the file and select "Open."
  3. When the Setup Wizard opens, click "Continue" in the bottom right to see the Malwarebytes Software License Agreement. Next, click "Continue," then "Agree."
