Report Processing error after updating from 2012 Q1 to Q2

[Dalila Uriarte]

My report runs fine in the viewer and you can still export it from the viewer, but programatically exporting the report now fails after going from 2012 Q1 to Q2 (6.0.12.215 to 6.1.12.611).

Code:
Telerik.Reporting.Report rpt = new TED.Web.Defender.DReport { DataSource = reportData };
Telerik.Reporting.Processing.ReportProcessor reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
Telerik.Reporting.InstanceReportSource instanceReportSource = new Telerik.Reporting.InstanceReportSource();
instanceReportSource.ReportDocument = rpt;
Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", instanceReportSource, null);

Error:

{"Object reference not set to an instance of an object."}

Hello John,

You should not experience such problems with the latest internal build. Please download it from your account, close all Visual Studio instances and install it on top of the existing Q2 installation (i.e. no need to uninstall previous version). Then go through the upgrade wizard.
