You may receive an error message when you try to install the UDDI Services database components on an instance of SQL Server 2005 that is running on a Windows Server 2003-based computer

Consider the following scenario. You try to install the Microsoft Windows Server 2003 Universal Description, Discovery, and Integration (UDDI) Services database components on an instance of Microsoft SQL Server 2005. The instance of SQL Server 2005 is running on a Windows Server 2003-based computer. In this scenario, you may receive the following error message:

This issue occurs because the UDDI installation process examines the value of the CSDVersion registry entry for SQL Server. The CSDVersion registry entry is used for SQL Server 2000 service packs. The CSDVersion registry entry is not used for SQL Server 2005. Therefore, this version check fails when you try to install the UDDI Services database components on an instance of SQL Server 2005.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this issue, add the CSDVersion registry entry to the Windows registry before you try to install the UDDI Services database components. To do this, follow these steps:

1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. If the instance of SQL Server 2005 is the default instance, locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\MSSQLServer\CurrentVersion
   If the instance of SQL Server 2005 is a named instance, locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\instance name\MSSQLServer\CurrentVersion
3. On the Edit menu, point to New, and then click String Value.
4. Type CSDVersion, and then press ENTER.
5. In the left pane, click CurrentVersion, and then note the default value for the CurrentVersion subkey in the right pane.
6. Double-click CSDVersion.
7. In the Value data box, enter the value that you noted in step 5, and then click OK.
8. Install the UDDI Services database components.
9. Delete the CSDVersion registry entry from the Windows registry.
