What is the "this" you're talking about?
It seems you're missing a file required for installation, have you tried reinstalling again/going through the setup process again?. As i don't see you mentioning that you tried installing it more then once.
Also as mentioned, contacting Microsoft might be your best bet if you are unable to get it installed.
