Deploy Crystal Report

Question

when I deployed crystal report on live it gave the following message

An error has occurred while attempting to load the Crystal Reports runtime.

Either the Crystal Reports registry key permissions are insufficient or the Crystal Reports runtime is not installed correctly.

Please install the appropriate Crystal Reports redistributable (CRRedist*.msi) containing the correct version of the Crystal Reports runtime (x86, x64, or Itanium) required.  Please go to http://www.businessobjects.com/support for more information.

Kindly help me...
