I have an earlier version - ArcSoft 5.5 - which will not work with my Windows 7 Professional. What version do I need to update?
You will need version 6 of the program because it has been developed to work on the following versions of the Windows operating system: Windows XP, Windows Vista, Windows 7, and Windows 8.
You can download a trial version of the program through the following link which will lead you to the official website: http://www.arcsoft.com/photostudio/features.html
