I searched a lot, but all are guessed answers. Help me to find the exact answer.

推荐答案

MSI是Windows Installer数据库. Windows Installer(随Windows一起安装的服务)使用它在系统上安装软件(即复制文件，设置注册表值等).

An MSI is a Windows Installer database. Windows Installer (a service installed with Windows) uses this to install software on your system (i.e. copy files, set registry values, etc...).

setup.exe可以是引导程序，也可以是非msi安装程序.非msi安装程序将从其本身提取安装资源并直接管理其安装.引导程序将包含MSI而不是单个文件.在这种情况下，setup.exe将调用Windows Installer来安装MSI.

A setup.exe may either be a bootstrapper or a non-msi installer. A non-msi installer will extract the installation resources from itself and manage their installation directly. A bootstrapper will contain an MSI instead of individual files. In this case, the setup.exe will call Windows Installer to install the MSI.

您可能要使用 setup.exe 的某些原因:

Some reasons you might want to use a setup.exe:

• Windows Installer一次仅允许安装一个MSI.这意味着很难让MSI安装其他MSI(例如，.NET框架或C ++运行时之类的依赖项).由于setup.exe不是MSI，因此可以用来按顺序安装多个MSI.
• 您可能希望更精确地控制安装的管理方式. MSI对于如何管理安装(包括安装，升级和卸载)具有非常具体的规则. setup.exe可以完全控制软件配置过程.仅当您确实需要额外的控制权时，才需要执行此操作，因为这需要大量的工作，并且要正确设置它可能会很棘手.

• Windows Installer only allows one MSI to be installing at a time. This means that it is difficult to have an MSI install other MSIs (e.g. dependencies like the .NET framework or C++ runtime). Since a setup.exe is not an MSI, it can be used to install several MSIs in sequence.
• You might want more precise control over how the installation is managed. An MSI has very specific rules about how it manages the installations, including installing, upgrading, and uninstalling. A setup.exe gives complete control over the software configuration process. This should only be done if you really need the extra control since it is a lot of work, and it can be tricky to get it right.
