Need advise on how to upgrade Adobe Acrobat Reader from 9.0 to 9.3

Hi,

We are trying to deploy Adobe Acrobat Reader 9.3. We are currently running 9.0.

We would like to use SCCM in order to perform the upgrade.

The upgrade path from 9.0 to 9.3 has to be done as follow:

9.1.1, 9.1.2, 9.1.3 and then 9.3.

I have donwloaded the following from http://www.adobe.com/support/downloads/product.jsp?platform=windows&product=10

The incremental updates:

AcroProExUpd910_all_incr.msp
AcrobatUpd911_all_incr.msp
AcrobatUpd912_all_incr.msp
AcrobatUpd913_all_incr.msp

AND the final

AcrobatUpd930_all_incr.msp (9.3)

However I am not sure what needs to be done with the .MSP file.

According to Adobe we could deploying Acrobat/Reader installer and patches as a single installation

http://kb2.adobe.com/cps/507/cpsid_50718.html

You have to have the following placed on the shared folder:

Contents of the Acrobat 9 Pro CD installer or unpacked electronic download
AcroProStdUpd910_T1T2_incr.msp (for example, 910 MSP update files for tiers 1 & 2 languages)
AcrobatUpd912_all_incr.msp (912 MSP update file)
AcrobatUpd913_all_incr.msp (913 MSP update file)

To run the installation in silent mode they have provided the following command.

msiexec.exe /i "[UNC PATH]\AcroPro.msi" PATCH="[UNCPATH]\AcroProStdUpd910_T1T2_incr.msp;[UNCPATH]AcrobatUpd912_all_incr.msp; [UNCPATH]AcrobatUpd913_all_incr.msp TRANSFORMS="1036.mst" /qn

1.) I am not sure how do the .MSP files work?
2.) I don't have the contents of the Acrobat 9 Pro where should we be getting them?
3.) Finally regarding the msiexec.exe I don't understand the "AcroPro.msi" where is this file? Perhaps will be part of the Acrobat 9 full content CD they mentioned before?  

If someone knows or have already gone through this process and want to give a hand with this I would appreciate any help!

Thanks!
