Don’t try this at home. I just got my new (new to me anyway) laptop set up nicely and then installed an instance of Denali CTP3 to start exploring. RTFM? Not me! The first thing I thought I’d play with was the tabular model and Project Crescent as this has huge potential for Reporting & BI people. So I click New Project and it says you can only do this on a default instance. Erm, but my default instance is 2008R2. Oh well, back to the (un)installer.
