Question

I have checked the version of Report viewer, its same...

Server Error in '/' Application.

The definition of this report is not valid or supported by this version of Reporting Services. The report definition may have been created with a later version of Reporting Services, or contain content that is not well-formed or not valid based on Reporting Services schemas. Details: Data at the root level is invalid. Line 1, position 1.
