I have checked it both the version are same. It is running fine on server machine if i open it through visual studio but if open it through IIS data is not showing in crystal report. when i checked the eventviwer of server machine then i found the below message:

The description for Event ID 4353 from source Crystal Reports cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. 

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

The keycode assembly, BusinessObjects.Licensing.KeycodeDecoder.dll, cannot be loaded. 

 the message resource is present but the message is not found in the string/message table.

 I have already reinstal crystal report on machine server.what is the solution. Please suggest me.
