推荐答案

检查这个文档，在标准 WIX 对话框中添加自定义对话框.您可以使用升级来查找以前安装的版本.

Check this document, to add Custom Dialog in standard WIX Dialogs.You can use Upgrade to find the previous version installed.

将 OnlyDetect 属性设置为 yes，以避免卸载以前的版本.

Set OnlyDetect attribute to yes, to avoid uninstall previous versions.

<Upgrade Id="{CE61D541-9988-4DA7-B748-7DF4355C6000}">
   <UpgradeVersion Property="PREVIOUSFOUND"
                   Minimum="1.0.0" IncludeMinimum="yes"
                   Maximum="$(var.Version)" IncludeMaximum="no"
                   OnlyDetect="yes"/>
</Upgrade>

使用 PREVIOUSFOUND 属性从欢迎对话框中发布上一版本存在对话框.

Use PREVIOUSFOUND property to publish the Previous Version exists dialog from Welcome Dialog.

<Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog"
         Value="PreviousVersionDlg">PREVIOUSFOUND</Publish>
