Click Save. It's in the bottom-right corner of the window. This will save your file in your selected folder.

Install the file. Go to the folder in which you saved the file (if you selected the Desktop folder, just minimize any open windows), then double-click it to open it and click Yes until you receive a notification that the registry file was successfully merged.

Click OK when prompted. This will appear on a prompt notifying you that your changes to the registry were successful.
