Finally getting around to this.
 
I've already got Platinum installed, and have melodyne and drum replacer and studio instruments already installed. So when asked by the new installer if I want to add them, I should not, right?

Yes, skip them.

Cool, thanks.

Yes, skip them.

I've been finishing off a project on the last Splat version, and plan to install CbB after that, without the addons & hopefully with ability to migrate the current settings on the install. Question: Are there any "up to date" Bandlab Assistant screen shots for all the steps involved mentioned above somewhere?
I'm assuming that under "...\Program Files\Cakewalk" parts of the "Shared" folders existing content get updated, for example the Sonitus dlls & inis in "Shared Plugins", for the core install, as was the case for a Splat update?.
Is there a list of the folder locations CbB specifically uses, those common with Splat and those distinct to CbB, for example in "...\AppData\Roaming" & "...\ProgramData"?
And last I'm assuming there are no conflicts with CbB and Splat using the same "...\Cakewalk Content" folder, and those custom or distinct files under "...\Cakewalk Content\SONAR Platinum\"  folders can just be copied to the equivalent ""...\Cakewalk Content\..." CbB folders.
 
I know some of this is info is has been incidentally mentioned in various posts but it's not always definitive or needs clarification, it would be really nice to have it officially in one place and current Cake Docs for "Installing Cakewalk" is sparse regarding the installation process and the "Bandlab Assistant" options. Having had issues with Splat installations in the past that needed to be resolved I'm maybe being overly cautious with CbB, but regardless I very much appreciate what the 2nd incarnation of the bakers and Meng are doing for all of us... Than You!!

The locations are similar to Platinum except the version folder names are "Cakewalk Core" instead of "SONAR Platinum." Themes are now stored in Cakewalk Content\Cakewalk Themes.
 
CbB installs like an upgrade.

Thanks for the response... Just to be sure...

What's in the drop down arrow & what happens after clicking install, does it offer to migrate current Splat settings, and how are addons prevented from being installed, this isn't shown or explained in the doc & that's part of what I wanted to find out. Thanks again for the swift response.
