Exchange Management Tools, RSAT, and Windows 7 SP1

I have a brand new computer with Windows 7 Professional. the first thing I did was install all updates to include SP1. When I attempted to install RSAT, I found I could not because of SP1 (someone forgot to do some testing). I then un-installed SP1 and installed RSAT. It installed successfully, but I then attempted to install Exchange 2010 SP1 management tools adn received the following error.

I then attempted to install both the IIS Web Management Tools and the Microsoft .NET Framework 3.5.1 from the "Turn Windows features on or off" dialog box. It failed on each attempt. I then installed SP1 and was able to add these features, however I still get the error above when attempting to install the Exchange 2010 SP1 management tools.

Am I missing something or is this a symtom of the previous issues with the RSAT installation? How can I fix this.
