SharePoint Integrated Reporting Services – Manifest does not match

After a successful, long and painful installation and configuration of SQL Reporting Services in SharePoint integrated mode with Kerberos I finally forced SSRS to work very nicely with my R&D SharePoint lab this week.

Yesterday I installed SQL Reporting Services and SP2 on an existing MOSS box in our integrated development environment. Installation and configuration of SSRS went smooth an easy up until I logged into Central Admin to configure Reporting Services. I received the following error:

The located assembly’s manifest definition does not match the assembly reference.”

The fix for my situation was simple – rerun the SQL Server Reporting Service install effectively repairing the server.
