Hi everyone,

I have a trouble modifying an old report, client wants to add a graphic in a report, Visual studio reporting services (no Crystal), not so hard I think myself, but now i'm struggling with an error:

Could not load file or assembly 'Miscosoft.ReportViewer.DataVisualization, Version = 10.0.0.0, Culture neutral, PublicKeyToken = b03f5f7f11d50a3a' or one of its dependencies.

That appears in the graphic area (not the whole report), other info in the report shows correctly.

The environment is Visual Studio 2008, visual Basic, SQL server 2008, SSRS 2008. Report runs as local report in WinForm app.

the Microsoft.ReportViewer.Common / Microsoft.ReportViewer.ProcessingObjectModel and Microsoft.ReportViewer.WinForms dlls in the proyect are pointing to version 10 (SSRS 2008)

Any ideas why the error?, all other reports (no graphics) works fine.

thanks in advance

I solved it, by replacing Microsoft.ReportVierwer.DataVisualization.dll from other development PC, delete reference to it from the proyect, re-add reference in the proyect.
Now works.
