Adobe Customization Wizard XI with Reader XI-not all options are available

I'm using the Adobe Reader XI redistributable (yes, I got the license and special download, etc.)

I've followed the Enterprise administration kit which makes me extract and build an AIP.  All is well

What I notice is that the Customization Wizard has some options grayed out.

For example, the DOCS for the customization wizard say that I can fill out username, organization, etc.

But those are grayed out.

Also, I cannot select the Installation Options -> Remove previous version of Acrobat (it's grayed out).  I can only select the Remove all versions of Reader.

Any idea why this is?

I point it to the AIP reader .MSI File when i built the customization kit.
