Cause: IIS application pool is not configured for the correct .NET Framework version, or the 32-bit setting is wrong. microsoft.reportviewer.common version 9.0.0.0 download

Solution:

Ensure your Application Pool uses .NET CLR Version 2.0 (for ReportViewer 9.0, even if your app targets .NET 4.x, it runs on CLR 2.0).
Enable Enable 32-Bit Applications = True if your app is x86.

Version Conflicts (Binding Redirects)

If your application is looking for version 9.0.0.0 but you have a newer version installed (like 10.0 or 14.0), you can add a binding redirect to your web.config or app.config file: Microsoft

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
      <assemblyIdentity name="Microsoft.ReportViewer.Common" 
                        publicKeyToken="89845dcd8080cc91" 
                        culture="neutral" />
      <bindingRedirect oldVersion="9.0.0.0-14.0.0.0" 
                       newVersion="14.0.0.0" />
    </dependentAssembly>
  </assemblyBinding>
</runtime>

(Change the newVersion to the version you actually have installed if you are upgrading). Error 2: Installation succeeds but runtime error persists

For Development Machines (Visual Studio)

Option B: Install the redistributable as above. Then, add a reference to C:\Program Files\Microsoft Visual Studio 10.0\ReportViewer\Microsoft.ReportViewer.Common.dll (or the appropriate path from the installer).
Set Copy Local = True for the reference in your project properties to avoid deployment issues.
