CourseBuilder for Dreamweaver

I have the Learning Suite 2.5 with Dreamweaver 5.5, but I can't seem to locate this extension.  I am using a old one, and I know here was a updated version of CourseBuilder.   I have checked the extension area off of the Adobe site and it's not listed anymore.  I have gone through all the folders on my install CD - E-Learning Suite 2.5 and through the install folders on my computer and I can't locate it.

Can someone please direct me to the location to install the updated version of this extension.

Thanks!
