I have sql 2008 R2 standard installed on my development machine (an msdn download). I am trying to install 2012 enterprise from my msdn dvd. I've gone through the analysis steps & passed. Doing the actual instance upgrade, I get the message "Rule 'SQL server 2012 feature upgrade' failed." The migration path in books on line says I should be able to do this upgrade. What's the deal?
