This version was installed in VAIO Windows 7 computers starting on June 2010 don't know when they changed or stopped including this version of software. The nice part of Media Gallery its that the installation creates the links from Media Center and it is a nice way of showing your Pictures & Videos with a very attractive music background. It keeps that "Sony VAIO" look to your setup and it also recognizes faces so it can show you pictures of just that person.
I don't know what other dependents are but I think PMB and Media Gallery must be installed so they both work. Help from the community its needed to understand which software has dependency from which one.
Even on the initial setup screen of Media Gallery it shows that it can launch VAIO Transfer Support. Also, VAIO Media Plus launches as it searches for content to display on Media Gallery. VCM intelligent Network Service Manager VAIO Analysis Manager Settings They both run as a result of Media Gallery so you need to install them as well.
