使用WIX的InstallDir UI扩展时,有条件地选择两个退出对话框

我正在为我的安装过程使用WIX的InstallDir_UI扩展的自定义版本.由于我想选择支持超链接控件(如果可用),我创建了两个不同的对话框：

<Dialog Id="NonHyperlinkExit" Width="370" Height="270" Title="!(loc.ExitDialog_Title)">
    <Control Id="Finish" Type="PushButton" X="236" Y="243" Width="56" Height="17" Default="yes" Cancel="yes" Text="!(loc.WixUIFinish)" />
    ...
    <Control Id="HowToLink" Type="Text" X="135" Y="175" Width="220" Height="10" Transparent="yes" NoPrefix="yes" Text="!(loc.InfoUrl)" />
    ...
</Dialog>

<Dialog Id="HyperlinkExit" Width="370" Height="270" Title="!(loc.ExitDialog_Title)">
    <Control Id="Finish" Type="PushButton" X="236" Y="243" Width="56" Height="17" Default="yes" Cancel="yes" Text="!(loc.WixUIFinish)" />
    ...
    <Control Id="HowToHyperLink" Type="Hyperlink" X="135" Y="175" Width="220" Height="10" Text="!(loc.InfoLink)" />
    ...
</Dialog>

然后,我修改了UI发布语句,以支持这些对话框,如下所示：

<Publish Dialog="NonHyperlinkExit" Control="Finish" Event="EndDialog" Value="Return" Order="998"><![CDATA[VersionMsi < "5.0"]]></Publish>
<Publish Dialog="HyperlinkExit" Control="Finish" Event="EndDialog" Value="Return" Order="999"><![CDATA[VersionMsi >= "5.0"]]></Publish>

运行此时,我收到以下错误：

error LGHT0204: ICE20: Exit dialog/action not found in 'AdminUISequence' Sequence Table. 
error LGHT0204: ICE82: This action HyperlinkExit has duplicate sequence number -1 in the table InstallUISequence

所以我试图改为修改InstallUISequence,但没什么帮助.试过这个：

<InstallUISequence>
    ...
    <Show Dialog="NonHyperlinkExit" Before="HyperlinkExit"><![CDATA[VersionMsi < "5.0"]]></Show>
    <Show Dialog="HyperlinkExit" OnExit="success"><![CDATA[VersionMsi >= "5.0"]]></Show>
</InstallUISequence>

但这只会给我以下错误：

error LGHT0177: The InstallUISequence table contains an action 'NonHyperlinkExit' that is scheduled to come before or after action 'HyperlinkExit',which is a special action which only occurs when the installer terminates.  
These special actions can be identified by their negative sequence numbers.  
Please schedule the action 'NonHyperlinkExit' to come before or after a different action.

任何有关如何创建条件退出对话框的想法将不胜感激.
