The custom executable program did not run during uninstallation in a Bundle project.

[BingoZha]

In a Bundle project, I have an executable program that I want to run before all packages are installed and also once before all packages are uninstalled. How can I achieve this?

Here is my bundle project .wxs file:
`

<Bundle Name="!(bind.packageName.Setup)" 
		Version="!(bind.packageVersion.Setup)" 
		Manufacturer="!(bind.packageManufacturer.Setup)"
		UpgradeCode="XXXXXXXX" 
		IconSourceFile="setup.ico">

	<BootstrapperApplication>
		<Payload Name="icon.ico" SourceFile="setup.ico" Compressed="yes" />
		<bal:WixStandardBootstrapperApplication LogoFile="setup.ico" LocalizationFile="Resources\HyperlinkTheme.wxl" ThemeFile="Resources\HyperlinkLargeTheme.xml" LicenseUrl="" ShowVersion="yes" SuppressRepair="yes" SuppressOptionsUI="yes" Theme="hyperlinkLargeLicense" />
	</BootstrapperApplication>


	<Chain>
		<PackageGroupRef Id="CloseMyApp" />
		<ExePackage Id="A"/>
		<MsiPackage Id="B"/>
	</Chain>
</Bundle>

`

It runs perfectly during installation,but it does not work during uninstallation even though i add the "UninstallArguments" argument.
