After Adobe Reader X 10.1.4 MUI deployment the version still appears as 10.0

I deployed Adobe Reader X through GPO in several steps:

Create a custom MST file using the Adobe Customization Wizard X found here:

http://www.adobe.com/support/downloads/detail.jsp?ftpID=4950

-> disable updates, prompts...

Download full version here:

http://www.adobe.com/support/downloads/product.jsp?product=10&platform=Windows

Copy Folder in a share and configure GPO using full version package and MST file

When updates are ready, download updates here:

http://www.adobe.com/support/downloads/product.jsp?product=10&platform=Windows

On you local computer, launch this command to encapsulate the .msp update into the .msi installer

from a DOS command prompt :

msiexec /a “C:\folderpath\Adobe Acrobat Reader X\AdbeRdr1010_en_US.msi” PATCH=”C:\folderpath\Adobe Acrobat Reader X\AdbeRdrUpd1011_Tier1.msp” /qb

Copy Folder in a share and configure GPO using updated full version package and MST file

The problem is that the version still appears as 10.0 in Help > About Acrobat Reader X...

Also 10.0 in the Control Panel > Programs and Features

Any idea why ?
