When crystal report calls an error 80040154 class not registered (exception from HRESULT)

I am using visual studio 2010 which is 32 bit software and i run this software on 64bit OS. I make a windows based application using c# and crystal report.

I have successfully deployed my project which has platform target: x86. This project successfully run on 32 bit windows 7 but when click on print button which calls crystal report object, Windows show an error

80040154 Class not registered (Exception from HRESULT :0x80040154(REGDB_E_CLASSNOTREG))."

i can't understand the above problem. I searched on google but no found perfect solution of this problem.
