SQL SERVER 2000 INSTALLATION/UNINSTALLATION ISSUES ON STANDALONE/CLUSTERED ENVIRONMENT


Consider a scenario where on an Active Passive Cluster, while uninstalling an instance of sql2000 patched with Service Pack 4, we see the following error after you click next on the screen where we enter the Virtual Server name.


 


‘The specified virtual server cannot be maintained by this version of setup’.


 


We are not able to proceed further because of the above error.


 


EXPLANATION(Resolution in one of my case)


=========================================


The registry key value for HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\MSSQLServer\CurrentVersion\CurrentVersion was set to 8.00.201. This value can be anything but not 8.00.194.


 


This key value should be 8.00.194 ,even when a service pack has been applied on Sql Server as in our case.


 


We changed the value of the CurrentVersion key to 8.00.194


 


After changing the value as mentioned above, the Uninstallation went fine.


 


Additional Information:


—————————–


We have seen cases, where while trying to upgrade from SQL Server 2000 standalone instance to a SQL Server 2000 clustered instance, In the Installation Selection page of the setup the “Upgrade, remove, or add components to an existing instance of SQL Server” option was grayed out


 


The above fixed this issue as well.
