3. Common Issues & Troubleshooting

Deployment and Installation

Unlike modern NuGet packages that are easily integrated via the Package Manager Console, version 9.0.0.0 typically requires the installation of a system-wide redistributable package or the inclusion of the assembly in the application’s deployment folder.

Common Deployment Methods:

1. Report Viewer Redistributable: Installing the "Microsoft Report Viewer Redistributable Package 2008" installs the assembly into the Global Assembly Cache (GAC).
2. Private Assembly Deployment: Developers often copy the Microsoft.ReportViewer.Common.dll directly into the bin folder of their application to ensure it loads without requiring a separate installer on the target machine.

For End-User Machines (Where the Application Runs)

1. Close all applications that may use .NET assemblies (e.g., Visual Studio, SQL Server Management Studio).
2. Run the installer as Administrator:
   • Right-click ReportViewer.exe → Run as administrator.
3. Accept the license terms and complete the installation wizard.
4. Verify installation:
   • Open a command prompt.
   • Navigate to C:\Windows\Assembly (for .NET Framework 2.0/3.5 GAC) or use gacutil /l Microsoft.ReportViewer.Common
   • You should see Version=9.0.0.0 listed.
5. Reboot (sometimes required for IIS integration).

Why You Might Need Version 9.0.0.0 Specifically

While newer versions (e.g., 12.0, 15.0) are available, developers often need version 9.0.0.0 for the following reasons:

1. Legacy Application Maintenance: Your company’s internal ERP, CRM, or invoicing system was built on .NET Framework 3.5 or 4.0 and uses ReportViewer 9.0.
2. Third-Party Vendor Lock: A vendor-supplied application explicitly references version 9.0.0.0. Upgrading the assembly would break compatibility.
3. SQL Server Compatibility: ReportViewer 9.0.0.0 was designed to work with SQL Server 2008 R2 Reporting Services. If your report server is on this version, the client-side controls must match.
4. No NuGet Reference: Older projects often rely on global assembly cache (GAC) references or local DLL references, not modern package management.

Error 2: Installation succeeds but runtime error persists in IIS

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

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.
