MindTouch announced in a Microsoft Port 25 guest blog entry that they released a beta of a Microsoft MSI installer for their Open Source Deki Wiki product. This lets you easily install a Wiki web application in a WIMP (Windows, IIS, MySQL, PHP) platform stack. The installer currently works with Windows Server 2008 and Windows Vista. You can read about my adventures installing it on Windows Server 2008 on the O'Reilly Inside Port 25 blog in two parts: Part 1 and Part 2.
