Instantiation of Export Options throws an Exception in SAP Crystal Report

Even after referencing the correct version of the dll, if you are still getting the error then it means that the runtime for the crystal reports is not properly installed.

I think you would have used MSI installer over EXE for the installation of SAP Crystal Reports however it has a shortcoming that the MSI installer does not properly incorporate Crystal Reports with Visual Studio.
