Can't view report in designer - VS 2012, Silverlight app

[Scot]

Hello,

I am trying to modify a report but when I go to view it in the designer I get the following error "Value cannot be null. Parameter name: instance".

I am using Microsoft Visual Studio Professional 2012 Version 11.0.61030.00 Update 4 on Windows 7 64 bit.  The project with the report controls is using .NET 4.0.

The Telerik.Reporting dll is version 5.1.11.928.  This is a legacy Silverlight app that I need to modify.  I have not "installed" the Telerik reporting application on my box.  I do not have access to that.  All the code and Telerik dlls were in our source control already.  I can build and run the reports with no issue but I need to modify them.  

Any help would be greatly appreciated.  Thank you!

Hello Scot,

You can run reports without an installation of Telerik Reporting. However, it is required to have Telerik Reporting installed on the machine in order to edit reports.

Thank you.  I was able to download the installer for that version and running it fixed the issue.
