Is it possible to use both Adobe Premiere Elements 10 with Adobe Photoshop Elements 9?
I don't want to upgrade Adobe Photoshop Elements 9 because has not enought new functions but need new Premiere with Organizer.
Does Adobe Photoshop Elements 9 will work correctly with Organizer of Premiere 10?
Yes, you can. Although the two programs will each use their own Organizers.
It is possible to use both of them, seperately though. If you wish to do use some interoperable feature, that wont be possible, since, as Steve said, they both use thier respective organizer.
