Creating a word report like report builder in Sql reporting services in Asp.net 2.0

I want to create a report just like report builder as provided by .net framework in word .User can drag and drop the fields in Ms word file .I started approaching to VSTO 2005.
I want to create Office projects using VSTO under visual studio 2005.
Is VSTO Free? I assumed that it is and i've followed the instructions from MSDN.
I've:
- installed office 2003 with its sp1,
- installed office interop assemblies: O2003PIA package - 5MB which came out from oxppia - self extractor 1,69MB
- used vstor.exe - 1,27MB
- used OfficeVSTOWindowsInstaller 187KB

I still don't see in my project types Office projects under New->Project and I can't open any samples as it shouts that this type is not supported...
