When I try to run the program, it will start running an installation process for Smartsound Quicktracks, but there's no such plugin in my computer. What is a "Smartsound Quicktracks" plugin anway? Is it recommended for my PC? Thank you in advance for your advice, Elliot

This plugin is required by QuickTime Player. Installing the latest version of the QuickTime Player should fix this problem. You can download the latest version of QuickTime Player from: https://www.apple.com/quicktime/download/win.html The free version of the player is available on the left hand side of the page.
