After stumbling upon this post http://sourceforge.net/projects/websitepanel/forums/forum/1126062/topic/3953118 I was able to solve my problem which was simply that the SERVER Service was set to manual and was not currently started.
I changed the Service to Automatic and Started it and was then able to successfully install WebsitePanel.
