On1 software

Anyone who previously purchased a (now) retired On1 product such as Perfect Effects 9.5 can no longer reinstall the software because the licensing service has changed, As an alternative On1 is providing a free download of On1 Photo 10.5.2. This includes ALL the modules, resize, effects, portrait etc, from the previous generation and doesn't need a license key. It is not the same as the free Photo 10 on the main webpage. Your email address is used to check previous purchases.
