If you’ve been waiting for the Click Once version of Report Builder 2.0, your wait is over (as long as you don’t mind using non-RTM bits).
The SP1 CTP will allow you to launch RB 1.0 or 2.0 as Click Once applications in both Native and MOSS integrated mode.
Have at it!
Oh, and how to do you turn it on? In native mode, go to Site Settings, then set Custom Report Builder launch URL to /ReportBuilder/ReportBuilder_2_0_0_0.application. MOSS integrated mode has a similar property which can be found in the Set Server Defaults link of the Reporting Services section of the Application Management inside the SPS Central Administration console.
