Remove "Change" and "Repair" buttons in Add or Remove Programs

I have created a Wix installer and have packed it in a bootstrap program.

When I execute the bootstrap program it creates the following entries in the registry :

alt text http://n2.nabble.com/file/n4011693/Up.jpg

When I run the bootstrap program it installs well and when I run the Add/Remove programs it shows "Change" button and "Repair" button. My requirement is that

• I want these two buttons to be one as "Change/Repair" like in other applications
• When I select this button I want my bootstrap program (setup.exe) to run and not the msi

This is my code area :

<Property Id="EXTUNINSTALL" Value="0"/>
<Property Id="UNINSTALLEXE" Value="msiexec.exe"/>

<!-- The Uninstall shortcut target executable & arguments-->
<CustomAction Id="SetUNINSTALLEXE_EXT" Property="UNINSTALLCMD"
