msi 安装程序中修复选项的用途是什么，它到底有什么作用(内部)? [英] What is the use of Repair option in a msi installer and what does it really do (internally)?
问题描述
我有一个使用 WIX 部署的软件包.当我安装后再次运行安装程序时，它提供了修复选项，它到底是做什么的?
I have a software package deployed using WIX. When I run the installer again after installing, it gives as option to repair, what does it exactly do?
推荐答案
修复:如果问题是修复做什么，那么它检查已安装产品的所有组件键路径，并安装任何可能丢失的组件 - 出于某种原因.从本质上讲，您的产品只是检查是否完全安装，然后修复错误.
Repair: If the question is what repair does, then it checks all component key-paths for the installed product and installs any components that may be missing - for some reason. In essence your product is just checked for being completely installed and then errors are fixed up.
修复意外重置注册表值时存在一些您应该注意的问题.此处描述了此问题以及 MSI 的许多其他常见问题(非常混乱的概述，但如果您发现任何相关问题，请略读):如何避免 WiX/MSI 部署解决方案中的常见设计缺陷?
There are some issues with repair resetting registry values unexpectedly that you should be aware of. This problem and a number of other, common problems with MSI are described here (very messy overview, but maybe have a skim if you see any relevant problems you recognize): How do I avoid common design flaws in my WiX / MSI deployment solution?
自我修复:您可能还因为设计错误触发了Windows Installer自我修复> 在您的 WiX 源文件/MSI 输出文件中.
Self-Repair: You may also have triggered a Windows Installer self-repair because of a design error in your WiX source file / MSI output file.
这是一种自行修复，无需您自己再次运行安装程序 - 或者从 添加/删除程序 开始.而是通过某些广告入口点"自动神奇地触发关键路径检查.例如，启动广告快捷方式或调用COM 类和一些其他类型的操作(参见链接内容).
This is a repair happening on its own without you running the installer again yourself - or kicking it off from Add/Remove programs. Rather it is automatically invoked via certain "advertised entry points" that trigger a key-path check auto-magically. For example the act of launching an advertised shortcut or invoking a COM class and a few other types of actions (see linked content).
我已经写了太多次关于自我修复的文章，我只会链接到现有答案.请先尝试最后一个(如何在您自己的包中避免它):
I have written about self-repair too many times, I will just link to existing answers. Please try the last one first (how to avoid it in your own package):
如果问题不是自我修复，那么您应该知道，当您再次运行安装程序时，出现修改/修复对话框是正常的，因为该产品已经安装.这是正确的行为.
If the issue is not self-repair, then you should know that when you run your installer again it is normal to get a modify / repair dialog because the product is already installed. It is the correct behavior.
