I installed this on a Windows 2008 server, but when I browse to the page, I get the following 500.19 error:

Cannot add duplicate collection entry of type 'add' with unique key attribute 'name' set to 'ScriptHandlerFactory'

Does anyone have any idea what went wrong?

So I take it that no one has any idea how to fix this?
