Removing a SQL Server Installation (64-bit)
This topic applies only to SQL Server 2000 (64-bit).
Use Add or Remove Programs in Control Panel to change or remove an instance of Microsoft® SQL Server™ 2000 (64-bit). When you remove the default or a named instance of SQL Server 2000, the data files and registry keys for the instance are deleted. To remove all instances of SQL Server 2000, each instance must be removed separately.
Note For a failover cluster installation, you cannot use Add or Remove Programs to remove an instance. You must use the Setup.exe graphical interface or the command line.
Tools and other shared files cannot be removed until all instances of SQL Server 2000 have been removed from a computer because these files are shared among all the installed instances. After SQL Server 2000 is uninstalled, some files may remain.
You can remove SQL Server from an instance without removing Analysis Services. However, because Analysis Services uses SQL Server core program files for its repository, Add or Remove Programs does not remove the SQL Server core program files from the instance unless you also remove Analysis Services. For more information, see Analysis Services (64-bit).
How to remove SQL Server 2000
Add or Remove Programs or Setup run from the desktop are the preferred methods to remove features, but the command line is useful for a silent operation or to maintain SQL Server using another application. You can use the /x="packagefile" argument on the setup command line to remove an instance of SQL Server 2000. Specify the name of the same installation package (.msi) file that was used to install the instance of SQL Server. Place the file in the same folder as Setup.exe. For more information, see SQL Server 2000 (64-bit) Setup Command.
If you do not know which .msi file was used to install the instance, then use the product code for the instance. The product code for the default instance can be gathered from the following registry key:
The product code for any named instance can be gathered from the following registry key:
HKEY_Local_Machine\Software\Microsoft SQL Server\instancename\Setup:ProductCode
