Microsoft has launched a free download manager, Web Platform Installer (PI) 1.0, for developers. The product is intended to make it simpler to install technologies such as .Net Framework 3.5, ASP.Net and Silverlight.

The tool installs Microsoft's entire Web Platform, including Internet Information Server, Visual Web Developer 2008 Express Edition and SQL Server 2008 Express Edition. With the installer interface, developers can install either specific products or the entire Web Platform. Web PI also offers the latest editions of the platform.

The tool provides an almost one-click download install of Microsoft's free web products, saving developers from having to go to different Web sites to install and configure these products, according to Microsoft.
