分享通过查找注册表进行的新版本安装？
我做了一个安装程序。里面启动项有一项为“查找注册表里确定的键值”，发现有该软件的旧版本才进行该升级安装。可是我在安装过该软件的机器上运行安装程序时发现提示“该版本已安装过...”不给安装。不明白原因。安装程序到底在机器上装了些什么？不是号称是“XCOPY”安装吗？

Updater Application Block Overview
By Edward Jezierski (Microsoft Corporation), Michael Stuart (Microsoft Corporation), Graeme Malcolm (Content Master Ltd), and Diego Gonzales (Lagash Systems)
June 2003
Summary: In medium to large organizations, it is common to want to keep all instances of a desktop application up to date with the latest version of executable files, library files, and other files. Ideally, administrators and support engineers like to deploy the updated files only once, to a central server, and have the updated files automatically replicate to each desktop installation. The Updater Application Block is a .NET solution that provides a "pull model" solution to automatically download application updates from a central location. It is designed for organizations who want the rich functionality of Windows Forms applications with the centralized manageability of Web-based applications, and who do not have the infrastructural requirements for "push model" solutions such as Microsoft® Systems Management Server (SMS). By using the Updater Application Block to download application updates, you can overcome the security "sandbox" limitations of downloading Windows Forms applications through a browser, while still maintaining control and security over the application update process.
