VS2010 does not find references to Crystal Reports10?

Why there is NO references of Crystal Reports 10 when I try to add them to my windows form application project in visual studio 2010?

I have installed Crystal Reports 10 recently (after installed VS2010) and tried to add some references such as 'CrystalDecisions.Shared, CrystalDecisions.CrystalReports.Engine, ...' to my project but actually, there is no references 开发者_StackOverflow社区in 'C:\Program Files\Common Files\Crystal Decisions\2.5\bin'

What's wrong?
