For the trial version of RTM, we will require the suite product or the trial suite product.  For the regular retail version, we will only require VS Pro.

 

Because CTP7 is based on our eval code, and because we're so close to shipping, we enabled this pre-req requirement for CTP7.  So to be able to install CTP7 you must have a copy of suite installed.  You can get the trial version here.
