Can you have version 12.0.0.0 alongside version 15.0 (Report Viewer 2022)? Technically yes – different versions have different assembly strong names and can coexist in the GAC. However, your application’s binding redirects must explicitly target the correct one. In practice, side-by-side installations can cause confusion for legacy apps. For stability, it’s often safer to use the exact version the application was compiled against.
If you must upgrade to a newer version (e.g., for security patches or modern browser support), you will likely need to:
After installation, confirm that version 12.0.0.0 is correctly registered.
| Section | Content |
|---------|---------|
| Header | Company logo, report title “Q3 2024 Sales Performance”, date range |
| KPI Summary | Total sales, YoY growth %, average order value, top-selling category |
| Main Table | Region, Sales Rep, Units Sold, Revenue, Target Achieved (%) |
| Chart | Bar chart: Monthly sales trend (Jul–Sep) |
| Footer | Page number, generated date, data source note |
This usually happens if your application was developed using a newer version of the Report Viewer (like Version 13, 14, or 15) but the server only has Version 12 installed.
Solution:
You must ensure your web.config file explicitly references the correct version. Look for the <assemblies> or <httpHandlers> sections and ensure they point to 12.0.0.0.
Example binding redirect (if you have other versions installed locally):
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Microsoft.ReportViewer.WebForms" publicKeyToken="89845dcd8080cc91" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-12.0.0.0" newVersion="12.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
