Web platform installer.. why? and how to install the SEO Toolkit?

How do you use the Web platform installer to install the SEO Toolkit from http://www.microsoft.com/web/spotlight/seo/? If I choose application, I have to choose an 开发者_运维百科application through a file dialog. If I choose OK, I get a 'The product you are trying to install is not supported on your operation system" message. What!? I am using Windows XP SP3.

and why this new way of installing applications? What's wrong with downloading an .exe. or .msi file? This thing seems to be made for newbies. It frustrated me instead of being anything better than the traditional previous installers.

If you don't want to use Web Platform Installer, then you can download the SEO toolkit from this page: http://www.iis.net/expand/SEOToolkit

The advantage of the WPI is that it automatically installs any dependencies required by the selected application.

SEO Toolkit requires IIS 7 or greater on the client machine running the tool, which means Vista or Windows 7.
