The error "This serial number is not for a qualifying product" typically occurs when you try to install the upgrade of an Adobe product on a new computer or new hard drive.
What is a qualifying product? Installing an upgrade of an Adobe product requires a qualifying previous product — a previous full version of the product that you bought and installed on your computer. If the previous version of the product exists on your computer, the upgrade starts automatically. If the upgrade installer can't find a previous version of the product on your computer, it asks you to enter the serial number of your previous product.
