如果删除文件，为什么MSI安装程序会重新配置? [英] Why does the MSI installer reconfigure if I delete a file?
问题描述
我已经在Visual Studio 2008中创建了一个MSI安装程序包.问题是，在安装后，如果我删除了任何已安装的文件，则会出现问题.这不是我的安装程序包的预期行为.我的文件安装属性为:
I have created an MSI installer package in Visual Studio 2008. The problem is that after install, if I delete ANY of the installed files. This is not my intended behavior for my installer package. My File installation properties are:
PackageAs vsdpaDefault 永久错误 只读错误 注册vsdrfDoNotRegister 系统错误 传递错误 重大错误
PackageAs vsdpaDefault Permanent False ReadOnly False Register vsdrfDoNotRegister System False Transitive False Vital False
如果这很简单，请原谅我.我无法相信我无法让Google放弃答案. :)
If this is trivial, please forgive me. I can't believe I have not been able to get Google to give up the answer. :)
推荐答案
Windows Installer 是一种部署技术，其作用是安装指定的文件并注册表设置，并将其保留在指定的安装位置，并确保它们是正确的版本-为此目的，自我修复或弹性是一种机制.它的操作与开发人员即时交换文件以进行调试，开发和测试的需求相冲突.
Windows Installer is a deployment technology, its job is to install the specified files and registry settings and keep them in the specified install locations and to ensure they are the right versions - self-repair or resiliency is a mechanism to that end. Its operation conflicts with a developer's need to exchange files on the fly for debugging, development and testing.
作为开发人员，您可能有兴趣部署MSI，然后即时删除或替换文件以进行调试.在这些情况下，MSI可能会令人讨厌，因为它永远不会停止执行其工作，并且会重新安装正确的文件.这称为"自我修复".可能会很烦人！ :-).
As a developer you may be interested in deploying your MSI and then deleting or replacing files on the fly to debug things. In these cases MSI can be a nuisance because it never stops doing its job and will reinstall the correct files. This is called "self-repair" and can be spectacularly annoying! :-).
有很多方法可以解决此问题，MSI非常复杂. 由于自我修复"通常从"advertised shortcut"调用此方法来避免此MSI功能的最简单方法是直接从文件系统而不是通过快捷方式启动EXE文件 .除了最复杂的EXE文件外，这将绕过MSI自修复机制.您还可以在桌面上手动创建一个非广告发布的快捷方式，该快捷方式不会触发自我修复(右键单击并按住可执行文件，同时按住鼠标右键，将其拖放到桌面上，然后在空白处释放按钮并点击在此处创建快捷方式").
There are a lot of ways to work around this, MSI is quite complex. Since the "self-repair" is normally invoked from an "advertised shortcut" the easiest way to avoid this MSI feature is to launch the EXE file directly from the file system and not via a shortcut. This bypasses the MSI self repair mechanism for all but the most complex EXE files. You can also manually create a non-advertised shortcut on the desktop that will not trigger a self-repair (right click and hold executable and whilst holding down the right mouse button, drag-and-drop to desktop and release button over an empty spot and click "Create shortcut here").
出于记录目的，自我修复由"自我修复入口点"；用于密钥路径验证.它们包括公告的快捷方式，文件关联，COM注册表数据等.
For the record self-repair is triggered by "self-repair entry points" for key-path validation. They include advertised shortcuts, file associations, COM registry data among other things.
There is a lot more to self-repair, or resiliency which is its official name, please check this comprehensive article on self-repair problems to find ways to resolve your specific problem. It is a long article, but it should be worth the read if you have self-repair problems.
