CrystalReportViewer item missing

I have installed Visual Studio 2010 Professional edition.

There was no Cystal Reports, so I downloaded "SAP Crystal Reports, version for Visual Studio" from SAP.

Now I can add CrystalReport.rpt as new item. But, there is no CrystalReportViewer item in toolbox.

I tried right click -> choose item. In Choose Toolbox Items dialog box CRV is checked, but still CRV is missing.

Need a help
