WiX Bundle升级：在删除旧版本之前安装新版本的MSI

我的问题是捆绑包升级.在升级中,捆绑包首先安装MSI的v_Next,然后取消安装v_revious的MSI.

我该如何更改此订单？我希望在升级中,在安装v_Next之前卸载MS_的v_Previous.

以下是我的包：

谢谢Rob的答案.我试图这样做,但它不起作用(我肯定会遗漏一些东西)……这就是我在MSI中所拥有的：

<Product Id="*"
         Name="MyProductName"
         Language="1033"
         Version="1.0.0.0"
         Manufacturer="MyCompanyName"
         UpgradeCode="aa027fd0-5111-1236-9af6-55581a588123">
    <Package InstallerVersion="200"
             Compressed="yes"
             InstallScope="perMachine" />
    <MajorUpgrade DowngradeErrorMessage="A newer version of MyProductName is already installed."
                  AllowDowngrades="no"/>
    <MediaTemplate />

    <Feature Id="ProductFeature"
             Title="MyProductName"
             Level="1">
        <ComponentRef Id="ApplicationShortcut" />
        <ComponentGroupRef Id="AllFiles" />
    </Feature>
</Product>

如果我运行v_previous MSI然后运行v_Next MSI(单独,不在捆绑包中),我将同时安装,因此不会执行升级.我究竟做错了什么？

没关系,MajorUpgrade正在运作.我的版本编号在vNext MSI中是错误的.我现在还需要添加次要的升级支持.
