解决方法
以下是我们使用的代码示例,我们实际上并没有在编译时设置URL,而是在MSI后期构建中更新属性,因此这可能看起来有点“过度设计”.我们使用WiX
ShellExec CA,并有额外的条件,以便网页仅在卸载期间显示,而不是在主要升级期间显示.
<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>
