Program Compatibility Assistant Manifest Not working in Vista32

Question

When I run my application "A driver Installer and Uninstaller Application", I am getting a "Program Compatibility Assistant" window once my exe get ended successfully. After going through the SO links and googling I couldnt find a solution to avoid "Program Compatibility Assistant" window in vista 32. I used the below manifest to avoid PCA and it works as expected (am not getting any PCA window in windows 7) but except windows vista 32? What should I do to make this work?

After Using the below manifest for my installer application I am not getting PCA window in windows 7 but it appears on windows vista 32-bit. How to avoid PCA window in vista32?

Here's the manifest I used:

 <?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

  </compatibility>
</asmv1:assembly>

The below is the snapshot of PCA window I get...

Update : the root cause I for the PCA window is "My Installer is not creating an entry in Add or Remove Programs". I made my app to make an entry in "Add or remove programs" and am not getting any PCA window. But I dont want to make an entry in Add or Remove Program.

Update 25-09-12: I have an executable say A.exe, which finds architecture of the OS and depends on the architecture it calls either A64.exe or A86.exe. In this case do I want to have manifests for all the exe's ( A.exe, A64.exe, A86.exe )? Right now I have manifest only for A.exe.

In order to opt out of PCA altogether, you will defintely need to include a manifest in all three of your executables.
