我制作了一个C＃wpf程序，此时我已准备好发布更新。我用Wix Toolkit创建了一个安装程序。所以我可以制作msi文件。但是，当我从版本1.0.0.0升级到2.0.0.0时，程序在安装后崩溃。如果我首先删除版本1.0.0.0的c＃程序，然后安装版本2.0.0.0一切正常。我不知道我做错了什么。这是我的Product.wxs（我的guid ID在我的程序真实ID中）：

答案 0 :(得分：3)
最可能的问题是日志中的消息：
禁止安装组件：{CCBFECA9-31FE-4D5C-A31A-5A264F69FD58}，因为存在具有更高版本密钥文件的相同组件
这意味着您没有更新该Dll的文件版本。结果是Dll丢失，您的应用程序崩溃。这里有一个很好的解释：
基本问题是，在安装的早期，它决定不会覆盖该文件，因为系统上的现有版本大于“新”传入文件，因此决定不安装它。这些是文件版本覆盖规则。但是，稍后升级会删除所有旧文件，但它仍然错误地认为它不应该安装该文件，因此在安装结束时它会丢失。
