windows installer - Wix Open web page when uninstall completes

Question

I'm using Wix3. I need to open a web page when the user uninstalls the product.
Any ideas how it can be done?

Thanks.

Here's a sample of the code we use, we don't actually set the URL at compile time, but update properties in the MSI post-build so this might seem a little "over engineered". We use the WiXShellExec CA and have an additional condition so that the webpage is only displayed during uninstall, and not during a major upgrade.

<Fragment>
    <Property Id="MyURL"><![CDATA[http://www.blah.blah.blah/]]></Property>
    <CustomAction Id="SetOpenURL" Property="WixShellExecTarget" Value="[MyURL]" />
    <CustomAction Id="OpenURL" BinaryKey="WixCA" DllEntry="WixShellExec" Impersonate="yes" Return="ignore" />

    <InstallExecuteSequence>
        <!-- Launch webpage during full uninstall, but not upgrade -->
        <Custom Action="SetOpenURL" After="InstallFinalize"><![CDATA[REMOVE ~= "ALL" AND NOT UPGRADINGPRODUCTCODE]]></Custom>
        <Custom Action="OpenURL" After="SetOpenURL"><![CDATA[REMOVE ~= "ALL" AND NOT UPGRADINGPRODUCTCODE]]></Custom>
    </InstallExecuteSequence>
</Fragment>
