Wix：インストール時とアンインストール時に別のURLを開く

Question

アプリのインストールとアンインストール時に異なるURLを開こうとしています。現在のところ、このセットアップではアンインストール時に両方のURLが開きますが、インストール時には何も表示されませ

<Property Id="InstallURL">$(var.HomepageURL)install?ver=$(var.VersionNumber)</Property> 
<Property Id="UninstallURL">$(var.HomepageURL)uninstall?ver=$(var.VersionNumber)</Property> 

<CustomAction Id="SetOpenInstallURL" Property="WixShellExecTarget" Value="[InstallURL]" /> 
<CustomAction Id="SetOpenUninstallURL" Property="WixShellExecTarget" Value="[UninstallURL]" /> 

<CustomAction Id="OpenInstallURL" BinaryKey="WixCA" DllEntry="WixShellExec" Impersonate="yes" Return="ignore" /> 
<CustomAction Id="OpenUninstallURL" BinaryKey="WixCA" DllEntry="WixShellExec" Impersonate="yes" Return="ignore" /> 

<InstallExecuteSequence> 
    <!-- Launch webpage during install --> 
    <Custom Action='SetOpenInstallURL' After='InstallFinalize'><![CDATA[Installed]]></Custom> 
    <Custom Action="OpenInstallURL" After="SetOpenInstallURL"></Custom> 
</InstallExecuteSequence>
