我按照Wix Open web page when uninstall completes
上的解决方案它可以工作，但我想修改解决方案，这样我就不必在使用light.exe时放置-ext WixUtilExtension
<Property Id="MyURL"><![CDATA[http://www.myurl.com/]]></Property>
<CustomAction Id="SetOpenURL" Property="WixShellExecTarget" Value="[MyURL]" />
<Binary Id="WixCA" SourceFile="C:\LocationOfFile\WixUtilExtension.dll" />
<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"></Custom>
<Custom Action="OpenURL" After="SetOpenURL"></Custom>
</InstallExecuteSequence>
但是，此解决方案不起作用。有人可以向我解释一下原因吗？
