We have installed the Crystal report 2016 on our new server, but while running the .rpt files we are receiving the below error: Error: An Error has occurred while attempting to load the Crystal Report runtime. Either the Crystal Report registry key permission are insufficient or the crystal report run time is not installed correctly. Please install the appropriate Crystal Reports redistributable(CRRedist*.msi) Containing the correct version of the Crystal report runtime(x86,x64 or Itannium) required.
