Hi all, I have downloaded zedgraph_dll_v514_464.zip from http://www.zedgraph.org and upload ZedGraph.dll and ZedGraph.Web.dll files into the Bin folder of my DNN Installation.

Finally, install the Chart Visualizer package (found in DesktopModules/Reports/Install/Visualizers) using the Manage Add-Ins page of the Reports Module.

I have set all the parameters(query ok, width, height, columns, ecc..)  for testing the chart but finally in the rendering of my reports I have found this error:

Si è verificato un errore critico
Impossibile caricare il file o l'assembly 'ZedGraph, Version=5.1.1.428, Culture=neutral, PublicKeyToken=02a83cbd123fcd60' o una delle relative dipendenze. La definizione di manifesto dell'assembly specificato non corrisponde al riferimento all'assembly. (Eccezione da HRESULT: 0x80131040)

In web.config i don't have any reference to any zedgraph dll.....

Where is the reference to assembly?

The only thing I can think of is to make sure you have the same version of ZedGraph as the module expects.  It should matter, but it might help.  It looks like the module is looking for version 5.1.1.428 of the ZedGraph.dll file.  Can you verify that the version in the Bin folder matches that?
