Troubleshooting and Downloading Microsoft.ReportViewer.Common Version 9.0.0.0
If you are maintaining a legacy .NET application, you have likely encountered the infamous error:
"Could not load file or assembly 'Microsoft.ReportViewer.Common, Version=9.0.0.0'." This specific assembly is a core component of the Report Viewer 2008
runtime, which allows applications to render and display reports designed with Microsoft reporting technology
Whether you're setting up a new development environment or deploying to a production server, here is how to find and install this specific version. Where to Download Version 9.0.0.0 Version 9.0.0.0 is specifically tied to Report Viewer 2008 Service Pack 1
. Because this is a legacy version, finding the direct standalone installer can sometimes be tricky on modern Microsoft pages. Official Redistributable : You can download the Report Viewer Redistributable 2008 Service Pack 1 directly from the Microsoft Download Center NuGet (For Developers) : If you need the DLLs for a project, the Microsoft.ReportViewer.Runtime.Common 9.0.21022.8 package is available via NuGet
. Using NuGet is often easier than manual installation as it manages the dependencies for you. Why Version 9.0.0.0? This version was released alongside Visual Studio 2008 microsoft.reportviewer.common version 9.0.0.0 download
. While newer versions like 2012 (v11.0) and 2015 (v12.0) are available, applications built specifically for the .NET Framework 3.5 often require the 9.0.0.0 assembly to remain compatible with older report definitions Common Fixes for Deployment Issues
If you have installed the runtime but still see "Assembly Not Found" errors, try these community-proven steps: Microsoft Report Viewer 2015 Runtime
In the world of .NET development, Microsoft.ReportViewer.Common version 9.0.0.0 is a legendary artifact from the late 2000s. It was the core engine for Visual Studio 2008 and SQL Server 2008 reporting, serving as the bridge that allowed developers to embed rich, interactive reports directly into Windows and Web applications. The Context: 2008 and the "Local Mode" Revolution
Before this version became a legacy headache, it was a breakthrough. Version 9.0 was the first to truly stabilize "Local Mode" (.rdlc files), which allowed reports to run entirely on the client’s machine without needing a full SQL Server Reporting Services (SSRS) instance. The "DLL Hell" Story
If you are looking for this specific version today, you’re likely living a classic developer "ghost story." Here is how the story usually goes:
The Legacy App: You inherit a mission-critical application built circa 2009. Troubleshooting and Downloading Microsoft
The Crash: You move it to a new server, and it immediately fails with the dreaded error: "Could not load file or assembly 'Microsoft.ReportViewer.Common, Version=9.0.0.0...".
The Compatibility Trap: You try to upgrade to a newer version (like 10.0 or 15.0), but the old .rdlc report definitions refuse to open or break because version 9.0 used a specific XML schema that newer viewers often try to "auto-upgrade"—sometimes irreversibly. Official Download & Recovery
To fix this, you must install the Report Viewer Redistributable 2008 Service Pack 1. Microsoft still hosts the official installer, though it is now considered legacy software.
Official Installer: Download the Report Viewer Redistributable 2008 SP1 from the Microsoft Download Center.
Alternative (NuGet): For modern environments, you can sometimes find these older runtimes packaged on NuGet as Microsoft.ReportViewer.Runtime.Common, specifically version 9.0.21022.8. Pro-Tips for Modern Systems
Common Errors and Fixes
2. Add assembly binding redirects in your web.config or app.config:
<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" newVersion="12.0.0.0" />
</dependentAssembly>
<!-- Repeat for .WebForms, .ProcessingObjectModel, etc -->
</assemblyBinding>
</runtime>
This way you don’t need the ancient 9.0.0.0 DLL at all. Common Errors and Fixes 2
Step 1: Determine Your .NET Framework Target
Version 9.0.0.0 is compatible with:
- .NET Framework 3.5 SP1
- .NET Framework 4.0, 4.5, 4.6, 4.7, 4.8 (may require binding redirects)
NuGet Installation

Cause: You have multiple versions (e.g., 10.0.0.0, 12.0.0.0) in the GAC, and the binding redirect fails.
Solution:
- Add a binding redirect to your
app.configorweb.config:<dependentAssembly> <assemblyIdentity name="Microsoft.ReportViewer.Common" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/> <bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0"/> </dependentAssembly> - Or uninstall newer ReportViewer versions if they are not required.
