The installation without Premiere works fine. There is no reason to install both and uninstall Premiere after it. I think the Help site tells it, because Encore normally comes with Premiere and some users are not smart enough to deselect Premiere during installation and wonder, why they suddenly have two versions of Premiere Pro.
And at all, this step wont let me avoid Photoshop Camera RAW of what I want...
Oh and no... the uninstall process wont let me uninstall additional components. Just Everything of nothing.
