Is it possible for a Windows application to download and install a new version of itself without the use of a Windows Service?

How would this work when using MSI based installations?

If the app checked periodically for a new version, eg. once per day, could the new MSI be downloaded and then installed automatically so that it replaced the existing version of the app?

Windows Installer 是用于在 Windows 上安装应用程序的 Windows 服务。它包含在所有当前版本的 Windows 中。因此，您无法在不运行该服务的情况下安装 Windows Installer 程序包。

如果系统上未安装 Windows Installer 服务，则需要使用Windows Installer Bootstrapping方法来安装该服务。
