Can any body please tell me reason why I'm getting this error.

The type 'CrystalDecisions.Web.CrystalReportViewer' exists in both 'c:\Windows\assembly\GAC_MSIL\CrystalDecisions.Web\12.0.2000.0__692fbea5521e1304\CrystalDecisions.Web.dll' and 'c:\Windows\assembly\GAC\CrystalDecisions.Web\12.0.1100.0__692fbea5521e1304\CrystalDecisions.Web.dll'

You added those DLL files:
  • c:\Windows\assembly\GAC_MSIL\CrystalDecisions.Web\12.0.2000.0__692fbea5521e1304\CrystalDecisions.Web.dll
  • c:\Windows\assembly\GAC\CrystalDecisions.Web\12.0.1100.0__692fbea5521e1304\CrystalDecisions.Web.dll
to your project.
The CrystalDecisions.Web.CrystalReportViewer class exists in both files.
You can try to remove one of them from your project (don't delete one of them from your hard disk!).

You need to remove one of the two references to one of the two DLLs that you added to your project.
