Reader 11.0.07 AIP - Errors during creation

I'm having fits trying to create an AIP for Adobe Reader 11.0.07.  Here's what I've done:

1.  Downloaded AdbeRdr11007_en_US.exe

2.  Extracted the setup files using the -nos_ne switch

3.  msiexec.exe /a path_to_extracted_files\AcroRead.msi - I get "Error 1334.   The file 'acroext.exe' cannot be installed..."

4.  I discover the Administrative Installation Points section of the Enterprise Administration Guild.

     4.1 - Step 5 confuses me - "Copy the installer files you downloaded to (AIP distribution point dir path)."  I downloaded an EXE.  I don't think that's what they mean, but I give it a try.  Same problem.

     4.2 - I copy the extracted files to be AIP that I created. I think Step 8 is misleading.  it tells me that I use the same .MSI as the source AND target for my AIP.  Doing this generates errors because I'm trying to read and write to the same .MSI.

5.  I discover the post Unable to install 11007 update via msi package and try the instructions there and I'm back to the 1334 error.  No joy.

6.  I followed the steps in this video, Creating an AIP for Acrobat XI | Acrobat IT Tips | Adobe TV, but I still get the 1334 errors.

Following the instructions in Unable to install 11007 update via msi package appears to have resolved the issue for others.  What am I doing wrong?
