Dont know if this is good to anyone, but search all these dlls:
- Microsoft.ReportViewer.Common.dll
- Microsoft.ReportViewer.ProcessingObjectModel.dll
- Microsoft.ReportViewer.WebForms.dll
- Microsoft.ReportViewer.WinForms.dll
- Microsoft.ReportViewer.DataVisualization.dll
You find them in C:\Windows\assembly\GAC_MSIL\...
, and then put them in the references of your project.
For each of them say: local copy, and check for 32 or 64 bit solution.
