On the pc which you have visual studio installed, navigate to the installation directory, there should be a folder called ReportViewer. this folder for me is at c:\\Program Files\Microsoft Visual Studio 8\ReportViewer.

This folder contains two of the above required dll, plus another dll for webforms.

The missing dll is the ProcessingObjectModel one. this is a bit tricky to get at.

Open command prompt as this will not work using windows explorer.

navigate to c:\windows\assembly

you should see a folder called Microsoft.ReportViewer.ProcessingObjectModel , navigate to that folder

this directory contains one or more folders depending upon the different versions of visual studio you have on your pc. If it is only visual studio 2005, there should be a folder called 8.0.0.0__b03f5f7f11d50a3a
{Note: there are two underscores in 0.0__b03 and not one }

open the folder and this folder should contain the ReportViewer.ProcessingObjectModel.dll file. copy it to somewhere accessible.

My Path is
C:\WINDOWS\assembly\GAC_MSIL\Microsoft.ReportViewer.ProcessingObjectModel\8.0.0.0__b03f5f7f11d50a3a
