crystal report deployment

Hello guys,

I've c# app with crystal report and I did the deployment part, then I start the program and use crystal report buttons in app it gives me this message:

System .typeinitializationException: The type initialize for
'CrystalDecisions.CrystalReportDocument'threw an exception
System.IO.FileNotFoundException:Could not load file or assembly
'CrystalDecisions. ReportAppServer. CommLayer,Version=13.0.2000.0, Culture=neutral,PublicKeyToken=692fbea5521e1304'or one of its dependencies. The system cannot find the file specified

Also ,I followed the website for the deployment
