Microsoft Web Platform Installer Release Candidate – Now works with XP and Windows 2003!

I’m excited to announce the availability of the Release Candidate version of the Microsoft Web Platform Installer (Web PI).  **Update 1/20/2009 - the final v1.0 release is now available!**

Web PI is a free tool that makes it simple to download and install the latest components of the Microsoft Web Platform, including IIS, ASP.NET, Visual Web Developer Express and SQL Server, along with a lot of cool IIS extensions like URL rewrite and ASP.NET MVC.

Web PI offers a simple experience for downloading and installing the entire stack through a single installer to help you obtain the software you need to build and run a complete Web solution on the Microsoft Web platform, whether you are using Windows XP, Windows Server 2003, Windows Vista, or Windows Server 2008.

Run Web PI to get started, and then run it again anytime to check for new extensions to the platform.  Every time Web PI is run it checks online to ensure the most current versions and new additions to the Microsoft Web Platform are downloaded.  Give Web PI a try today!



  • I don't believe xp is supported because IIS 7 can't run on xp!

  • XP is supported, but Web PI installs IIS 5.1 on XP...which is the supported version of IIS on that platform. Likewise, it installs IIS6 on Windows 2003.

  • What about XP Home? Will IIS 5.1 be installed on XP Home?

  • Unfortunately XP home is not supported. IIS 5.1 is only available on XP Professional and above. If your computer can run it, I recommend going to Vista Premium or above, where IIS7 is available.

  • iis7.0 no run for xp

  • Initial attempt to run the wpilauncher.exe generate:

    Cannot load product.xml from

    which in turn renders:

    I suspect my XP host lacks

  • I just installed Win 2003 Server Enterprise clean, but this error immediately pops up after running the install:

    The 'META' start tag on line 3 does not match the end tag of 'HEAD'. Line 4, position 3.

    Then it exits.

  • Those of you experiencing issues, please also post this information to thanks!

  • I've installed Visual C#Express and .NET Framework 3.51. But running the MS Web Platform Installer under XP SP2+ (german) produces an german error-message. On english: "The 'META' start tag on line 3 does not match the end tag of 'HEAD'. Line 4, position 3". Then it exits. Reading the other comments it should be a known bug, any solution?

  • I tried to install WebPI on XP sp3, All installation was good.
    but I got error of "Cannot load Microsoft.Web.Administration, Version=, Culture=neutral, PulicKeyToken=....
    when I click the server listed in Connections at IIS Manager.
    Absoluttely I logged in as Administrator, ...
    Someone had the same problem, but no right answers, see

  • Thanks for the great feedback. We've investigated the issue, "The 'META' start tag on line 3 does not match the end tag of 'HEAD'. Line 4, position 3." This is an issue on our side that we will be resolving in our next release.

    As a workaround in the meantime you should go to your local app data directory and delete any xml files with "productCache" in the title. On Windows 2003 the location is here: \Documents and Settings\\Application Data\Microsoft\Web Platform Installer . If this still does not fix your issue please report it on the forums and we can continue to help you there! Thanks.

  • I also had this META tag error on W2K8 (x64) - resolved by deleting the productCache file in AppData\Local\Microsoft'Web Platform Installer

  • Same on Vista Business x32.

  • same meta error on win 2003 server web edition and win 2008 server web edition. workaround doesn't work as there is no such directory present!
