在 Wix 中满足条件时显示警告对话框

Question

在我的 Wix 安装程序中，我正在搜索 Adobe acrobat reader 的注册表项并显示带有“是”和“否”选项的警告对话框。如果未安装 Adobe reader，WelcomeDlg 允许用户“继续”或“退出”安装，此对话框应在安装序列期间立即显示。

我在我的代码中发现一个问题，因为“AdobePrerequisiteDlg”不支持“ADOBEREADERINSTALLED”属性，即使注册表项存在，该对话框也会显示。

警告对话框“AdobePrerequisiteDlg”仅应在属性“ADOBEREADERINSTALLED”不满足时显示（即注册表项不存在），但到目前为止，这还没有发生，因为我每次都能看到对话框显示。

我尝试了很多更改，但无法找出问题所在。这是我的代码：

Answer 1

首先，您需要括号或双 NOT 条件：NOT (Installed AND ADOBEREADERINSTALLED) OR NOT Installed AND NOT ADOBEREADERINSTALLED

然后。启动安装程序时是否看到 WelcomeDialog？还是 AdobePrerequisiteDlg 先行？如果是第二个变体，您需要对代码进行一些更改。试试这个：

在自定义 UI 中添加对自定义对话框的引用。
UIRef 应指向自定义 UI，而不是描述自定义对话框的 UI。
在您的自定义 UI 中描述对话的所有变体和步骤。（见下面的例子）
条件语句应该放在 Publish 元素中。
安装UI不需要序列。
