Hye..I want to ask a question about error that I received when I try to drag a chart from toolbox to design surface of report.rdlc. I'm using SAP Crystal Reports, version for Visual Studio 2010. But unfortunately, I got this error :

Could not load file or assembly 'Interop.CrystalReportsCommonObjectModelLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

I already have that kind of library in my reference folder.

I took about more than a week to solve this problem but I failed to.
Please guide me on how to solve this problem.
Thanks in advance..
