Recently I modified one of my SSRS projects to use ReportViewerControl 2010 version instead of the old version by downloading the control from here http://www.microsoft.com/downloads/details.aspx?FamilyID=a941c6b2-64dd-4d03-9ca7-4017a0d164fd&displaylang=en.
After compiling my project and publishing it I tried to run the report and ran into the error
Remote report processing requires Microsoft SQL Server 2008 Reporting Services or later.
After a bit of surfing I realized that the prerequisites in the microsoft download page of the control listed this
- Microsoft SQL Server 2008 Reporting Services or higher for server processing mode
- .NET Framework 3.5 SP1 or .NET Framework 4.0
Hmm. Strange. So be careful before you migrate your report viewer control for your SSRS projects from version 2008 to 2010. Make sure you have SQL Server 2008 at the server.
