Reporting - error when run on server

[asemwhy]

Report run nicely on localhost but produced the following error message when we run on server (production). It happened after we upgrade from  5.3.12.119.

Could not load type 'Telerik.Reporting.Processing.ParametersManager`1' from assembly 'Telerik.Reporting, Version=6.2.13.110, Culture=neutral, PublicKeyToken=a9d7983dfcc261be'.

at Telerik.ReportViewer.WebForms.ParametersPage.OnPreLoad(EventArgs e)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)


Please help

Hello,

Please, check whether Telerik.Reporting.dll assembly is correctly uploaded to the server and the versions of all the references to the Reporting assemblies: project references, assembly references from the web.config file, the web pages and user controls (.aspx, .ascx). For the project references, check whether the Copy Local attribute is set to true.

Kind regards,

Hi Safie,

You can find how to set the Copy Local property in this MSDN article. Also, please check the References to Shared Components at the Run Time section here.
We believe that some of the dll's you're referencing are missing on the deployment machine. Once you deploy the project, please be sure that all the dll's are deployed too. 

Kind regards,
