Could not load file or assembly Microsoft.ReportViewer.WebForms.XmlSerializers

Question

i am using ReportViewer control in my aspx page. i am accessing the report from remote processing mode.

this is my code:

      ReportServerDomain = System.Configuration.ConfigurationSettings.AppSettings["ReportServerDomain"];

       ReportServerUserName = System.Configuration.ConfigurationSettings.AppSettings["ReportServerUserName"];

       ReportServerPassword = System.Configuration.ConfigurationSettings.AppSettings["ReportServerPassword"];

       String ReportFolder = System.Configuration.ConfigurationSettings.AppSettings["ReportFolderName"];

       rptUrl = new Uri(Convert.ToString(System.Configuration.ConfigurationSettings.AppSettings["ReportURL"]));

       IReportServerCredentials irsc = new CustomReportCredentialsToCreateStatement(ReportServerUserName, ReportServerPassword, ReportServerDomain);

       ReportViewer1.ServerReport.ReportServerCredentials = irsc;     

       ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote;

       parameters = new ReportParameter[1];

       parameters[0] = new ReportParameter("ClientStatementBatchId", ds.Tables["ClientStatemtntBatch"].Rows[0]["ClientStatementBatchID"].ToString());

       ReportViewer1.ServerReport.ReportServerUrl = rptUrl;

       ReportViewer1.ServerReport.ReportPath = "/" + ReportFolder + "/Client Statements";


       ReportViewer1.ServerReport.SetParameters(parameters);    // i am getting error on this line.

       ReportViewer1.ServerReport.Refresh();

The error is:

Could not load file or assembly 'Microsoft.ReportViewer.WebForms.XmlSerializers, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

Can any one help me , how to solve this issue?

Have you tried to reinstall ReportViewer redistributable files? You can find the links here

http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=6576

The first one is the one related to VS2008 report viewer, ( the other one is for 2005 version) and is the one that should resolve your problem.
