Error with Report Viewer

Hi, I am getting the following error when I try to open up my web application now, after installing the report viewer add on and placing it onto one of my pages.

Parser Error Message: Could not load file or assembly 'Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=nutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system could not find the file specified.

Source Error:
Line 47: <add assembly="Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />

Source File: web.config

So far I have tried to fix this error by installing the reportviewer.exe on the server. I have also verified that the ReportViewer files are in the assembly folder on the server. I also found a site saying to run the reportviewer.exe from a specific location, here is the link

http://dotnetslackers.com/_NET/re-49414_Could_not_load_file_or_assembly_Microsoft_ReportViewer_WebForms.aspx

but when I try to browse to the folder it is talking about I found out that I don't even have a BootStrapper folder under Microsoft Visual Studio 8/SDK/v2.0

Does anyone have any ideas on how to fix this error?

HI,

This error is caused by a missing dll. This dll is part of your visual studio libraries and resides somewhere in your visual studio directory. For me it is: C:\Program Files\Microsoft Visual Studio 9.0\ReportViewer
Solution:
Go to the reference management screen and make sure that the following dll files are copied localy
Microsoft.ReportViewer.Common.dll
Microsoft.ReportViewer.WebForms.dll

Alternative solution:
You need to copy Microsoft.ReportViewer.Common.dll and Microsoft.ReportViewer.WebForms.dll to your website bin folder.

Good Luck!!!
