Trying to install Win XP mode

OK!

I updated my G-MA790X-UD4P from the @BIOS. First time went through the built in link to server and it SAID it was updating to the latest version (F9) but after going through all the hoops (and getting the same error message) I foind it actually only upgraded to the 5a BIOS.

Went back to the Gigabyte d/l site and got ver. 9 and then back to @BIOS to install it. Reset all my BIOS settings, booted up and then completed the install of XPMode without a hitch.

Its up and running as we speak.

I am running Win 7 Ultimate (RTM) fully patched & up to date.
BIOS is the latest for this system. Hardware-Assisted Virtulization Tool confirms
that this PC is able to run virtual mode. (Havdetectiontool.exe & Securable.exe)
Files downloaded from:
Download Windows XP Mode
I run WindowsXPMode.exe installer. It says it is installing, and then it says it is finished. It doesn't show up in the start menu like it should. (See instructions from MS below). I have installed and uninstalled this several times and always the result is the same.

(Once you have installed Windows XP Mode, click the Windows 7 Start button , then select All Programs > Windows Virtual PC > Windows XP Mode to begin setup. For information on how to set up Windows Virtual PC and Windows XP Mode, check out "Running Windows XP Mode with Windows Virtual PC".)

The install path, is:- "c:\program files\windows xp mode"
This folder contains the following folders and files:

KEY.txt
VXPEULA.txt
Windows XP Mode base.vhd
A folder called Tutorial which has a few html and gif files.

If I attempt to run Windows6.1..KB958559-x64.msu I get the following message:
The update is not applicable to your computer.

Does anyone have an idea as to what the problem is?
The system spec:
Acer Travelmate 7520
