Symptoms
If you have recently upgraded your instance of SQL Server Reporting Services (SharePoint mode) to Cumulative Update 5 (CU5) for SQL Server 2012 Service Pack 3 (SP3), you may experience an issue in which your Alerts or Subscriptions are not working as expected. Additionally, you may also notice the following error message logged in the Reporting Services log files:
w3wp!library!1ac!10/05/2016-09:02:29:: e ERROR: Throwing Microsoft.ReportingServices.Library.InvalidReportServerDatabaseException: , Microsoft.ReportingServices.Library.InvalidReportServerDatabaseException: The version of the report server database is either in a format that is not valid, or it cannot be read. The found version is '164'. The expected version is '163'.;
Cause
This issue occurs because of a change that was made to the database that incremented the database version number during the installation of CU5 for SQL Server 2012 SP3.
