如何确保在使用WiX显示UI后运行FindRelatedProducts？

但是,FindRelatedProducts报告当前安装是按用户.

MSI(c)(A4：F0)[13：33：20：490]：FindRelatedProducts：**当前安装是按用户**.产品’<< my guid>>’的相关安装是每台机器.跳绳…

从日志中我可以看到,只有在FindRelatedProducts运行后才会创建ALLUSERS属性(注意时间戳)：

MSI(c)(A4：A8)[13：33：25：032]：属性更改：添加ALLUSERS属性.它的值是’2′.

ALLUSERS属性是根据用户选择的内容从UI发布的：

<Publish Property="ALLUSERS" Value="2"><![CDATA[FolderForm_AllUsers="ALL" AND VersionNT>=400 AND Privileged=1 AND FolderForm_AllUsersVisible=1]]></Publish>
      <Publish Property="ALLUSERS" Value="{}"><![CDATA[FolderForm_AllUsers="ME" AND VersionNT>=400 AND Privileged=1 AND FolderForm_AllUsersVisible=1]]></Publish>


    <Control Id="AllUsersRadioGroup" Type="RadioButtonGroup" X="20" Y="175" Width="342" Height="42" Property="FolderForm_AllUsers" Text ="empty">      
      <RadioButtonGroup Property="FolderForm_AllUsers">
        <RadioButton Value="ALL" X="0" Y="0" Width="342" Height="17" Text="$(loc.InstallForAll)" />
        <RadioButton Value="ME" X="0" Y="18" Width="342" Height="17" Text="$(loc.InstallForMe)" />
      </RadioButtonGroup>

      <Condition Action="show"><![CDATA[VersionNT>=400 AND Privileged=1 AND FolderForm_AllUsersVisible=1]]></Condition>
      <Condition Action="hide"><![CDATA[NOT (VersionNT>=400 AND Privileged=1 AND FolderForm_AllUsersVisible=1)]]></Condition>
    </Control>

因此,新版本与现有版本一起安装(添加/删除程序中存在两个条目).

<InstallUISequence>
  <Custom Action="VSDCA_FolderForm_AllUsers" After="IsolateComponents"><![CDATA[Installed="" AND NOT RESUME AND ALLUSERS=1]]></Custom>
  <Custom Action="PreventDowngrading" After="FindRelatedProducts">NEWPRODUCTFOUND</Custom>
</InstallUISequence>


<InstallExecuteSequence>
  <!-- Only schedule this custom action for the 32-bit MSI.  -->
  <?if $(var.DependenciesPlatform)=x86 ?>
  <Custom Action="CA_Err32BitMsiOn64BitOS" After="LaunchConditions">
    <![CDATA[MsiAMD64 OR Intel64]]>
  </Custom>
  <?endif ?>

  <!-- Prevent downgrading -->
  <Custom Action="PreventDowngrading" After="FindRelatedProducts">NEWPRODUCTFOUND</Custom>

  <RemoveExistingProducts Before="InstallInitialize" />

  <Custom Action="LaunchApp" After="InstallFinalize" />

  <InstallInitialize></InstallInitialize>
  <RemoveShortcuts></RemoveShortcuts>
  <InstallFiles></InstallFiles>
  <CreateShortcuts></CreateShortcuts>
  <InstallFinalize></InstallFinalize>

  <ScheduleReboot After="InstallFinalize"/>
</InstallExecuteSequence>

只有在每台机器上安装了两个版本的应用程序时才会出现这种情况,因为FindRelatedProducts显然假定每个用户安装(因为它在用户能够选择其中一个单选按钮之前运行,因此没有设置ALLUSERS属性它运行的时间).

如何确保只有在用户指定的UI中发布ALLUSERS后才执行FindRelatedProducts？
