Frame 12 install options question

In the Frame 12 install, a box comes up with Options:

-Adobe Framemaker 12  1.3 GB

On the side panel is a tick box with Adobe Framemaker and then indented under that is Adobe PDF Creation Add-On XI 156 MB

-Adobe ExtendScript Toolkit CC

Here are my questions:

Is the "Adobe PDF Creation Add-On XI 156 MB" a crippled Acrobat XI?

(I've been told yes. As I have Professional Acrobat XI, I don't want this.)

If I uncheck the "Adobe PDF Creation Add-On XI", it unchecks the Adobe Framemaker12 box above it

BUT DOES NOT UNCHECK the Adobe Framemaker 12 (1.3 GB) box on the left.

I can't find any documentation about what is included in this package.

Do I want these files?
