如何让WiX主要升级工作?

我正在努力启用WiX的主要升级功能.

我希望安装程序的每个新版本都是一个主要的升级(完全卸载,然后是新安装),因为我们不希望不同的升级和干净的安装版本.

我开始尝试使用标签的东西,但我一直在“安装另一个版本”.运行安装程序时出现错误信息.

所以我实现了V3.5中添加的新标签,使升级更容易.我仍然收到错误消息.

然后,我读到某个地方,您需要更改每个新版本的ID GUID.所以我设置Id =“*”让WiX生成它们.

现在,当我安装较新的版本,它不会卸载旧版本,最后两个安装到同一个文件夹.我这样做是因为运行MSI(新的或旧的)会启动修复/删除屏幕.

此外,该程序未被新版本覆盖.

这是WiX脚本的开始:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">

    <Product Id="*"
             Name="Foo"

             Codepage="1252"
             Version="!(bind.FileVersion.Foo.exe)"
             Manufacturer="Foo Bar Ltd."
             UpgradeCode="dac2fab2-7d76-4e47-b25f-0748380dab81">

        <Package
                 Description="Foo"
                 Comments="This installer database contains the logic and data required to install Foo."
                 InstallerVersion="300"
                 Languages="1033"
                 SummaryCodepage="1252"
                 Platform="x86"
                 Compressed="yes" />

        <!-- Remove older versions -->
        <!-- Important note: MSI ignores the last version digit 1.0.0.? when comparing versions, so always change at least the 3rd digit for new external releases-->
        <MajorUpgrade DowngradeErrorMessage="The version currently installed is newer than the version you are attempting to install."/>
这是一个我所用的所有软件包的代码片段,在许多内部和公开发行版本上进行了改进
