Symptoms
Consider the following scenario:Both Microsoft SQL Server 2005 Reporting Services and Microsoft SQL Server 2008 Reporting Services are installed on a computer.You start Reporting Services Configuration Manager by using SQL Server Configuration Manager.In this scenario, Reporting Services Configuration Manager for SQL Server 2005 Reporting Services starts instead of Reporting Services Configuration Manager for SQL Server 2008 Reporting Services. Additionally, the instances of both SQL Server 2005 and SQL Server 2008 appear in the Instance Name list.
Resolution
This issue occurs because SQL Server Configuration Manager uses the SQL Server 2005 registry key to obtain the executable path for Reporting Services Configuration Manager instead of using SQL Server 2008 registry key.
