我有一个 Windows 窗体应用程序的 Wix 安装程序，并且我正在使用 WixUI_InstallDir UI 集。 首次安装应用程序时，用户可以选择安装应用程序的文件夹，默认为 ProgramFilesx86 文件夹，但用户可以根据需要安装到其他文件夹。 问题是，当用户安装较新版本的应用程序并运行安装程序时，他们将不会获得选择文件夹的选项，因为它是升级，但如果用户安装了原始版本并运行升级安装程序会卸载原始版本并将升级版本安装到默认文件夹。
我是 Wix 的新手，所以我还没有真正尝试过任何东西，因为我现在不知道从哪里开始？
这是我设置UI模式的地方：
<ui:WixUI Id="CustomWixUI_InstallDir" InstallDirectory="INSTALLFOLDER">
</ui:WixUI>
这是我的文件夹配置：
<StandardDirectory Id="ProgramFiles6432Folder">
<Directory Id="CompanyFolder" Name="!(bind.Property.Manufacturer)">
<Directory Id="INSTALLFOLDER" Name="!(bind.Property.ProductName)">
这是 Custum UI xml：

这可以通过将安装文件夹添加到注册表并创建一个保存该值的属性来解决。
像这样： 在片段中的某处添加以下内容：
<RegistryValue Root="HKCU" Key="Software\[Manufacturer]\[ProductName]" Type="string" Value="[INSTALLFOLDER]" Name="InstallDir" />
然后在 UI 初始化之前添加以下内容：
<Property Id="INSTALLFOLDER">
<RegistrySearch Id="InstallFolderRegKey" Root="HKCU" Key="Software\[Manufacturer]\[ProductName]" Name="InstallDir" Type="raw"/>
</Property>
在这种情况下 INSTALLFOLDER 也是所有组件所在文件夹的 id：
<StandardDirectory Id="ProgramFiles6432Folder">
<Directory Id="CompanyFolder" Name="!(bind.Property.Manufacturer)">
<Directory Id="INSTALLFOLDER" Name="!(bind.Property.ProductName)">
还有我在 wix UI 中放入的内容：
<ui:WixUI Id="CustomWixUI_InstallDir" InstallDirectory="INSTALLFOLDER">
</ui:WixUI>
