Rapture Session addition to Sonar Platinum vs. Rapture and avoiding sample duplication

I was debating whether to post in the Sonar forum or the Cakewalk Instruments column; so please pardon my ignorance if I got this in the wrong forum.  Maybe I will post in both.  Although I'm a longtime Cakewalk user, I am relatively unenlightened when it comes to soft synths.  Among others which have come with previous Sonar releases, I have Rapture installed; but I haven't made any real attempt to learn it.  Now, with Rapture Session on the scene, I was about to install it. I got to where you choose the directories to install programs and presets, and sample content and I see that the directory does not yet exist. So, it appears that, although Rapture Session says it uses Rapture sound samples, it is either going to install duplicates of everything or different content.  Because of its learning curve (as I said above, I'm not primarily using Sonar for synth music) I have not really used Rapture.  So, should I remove Rapture and install Rapture Session, or is it possible to point the Session installation directory pointers to the existing Rapture program and sample directories?  Currently, it appears the sample content is under Program Data\Cakewalk\Rapture and the multi-samples appear to be under program files\Cakewalk Rapture (And ... I see some directories for Rapture LE which I didn't even know I had installed elsewhere on the computer).  So, how do I avoid making this worse?  Any help would be appreciated.
