Acrobat XI Pro via Creative Cloud installs twice on Win 8.1 Desktop

Question

I am running Windows 8.1 Pro, 64 bit on an HP Pavilion a6700y desktop PC using Adobe Create Cloud. When I install Acrobat XI Pro, it installs twice. One version is Adobe Acrobat XI Version 11.0 with a size of 1.8 MB and the other is Version 11.0.00 with the size of 2.0MB.
Does anyone know why this happens. Nothing seems to differentiate the two, and if I uninstall one, both uninstall. I did uninstall, clean the registry and tried reinstalling the program, and the same two versions display. I am not getting an indication that one is 64 bit and the other 32 bit, so I can't differentiated them.
Any suggestions?

It's because Acrobat's MSI makes an entry in the Add/Remove Programs control panel and then the Creative Cloud MSI makes a separate but similar entry in the Add/Remove control panel.  It's documented in a couple of places but here is the most convenient for demonstrating it.  It's in the uninstallation process:

(Documenation Excerpt)
Uninstalling Acrobat on Windows
Once you have deployed Acrobat using the package in the Exceptions folder, you can uninstall it using the usual process for uninstalling msi packages. There are two MSI packages that are necessary to uninstall in a standalone package.  One for the main MSI package that the Creative Cloud Packager creates which is for licensing and the second MSI package which is the Acrobat Pro MSI package which is in the Exceptions folder. 
Here is the command line syntax for uninstalling Acrobat:
Syntax Example:
msiexec.exe /x <path to Acrobat msi file> /qn
Here is the command line syntax for uninstalling the Creative Cloud Packager licensing package:
Syntax Example:
msiexec.exe /uninstall <path to the CCP msi file> /quiet
