Clean Up the Registry
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
The Msizap.exe tool removes only Windows Installer specific keys or data for the ProductCode. It is best to manually remove the MSDE 2000 registry keys. Use Registry Editor to remove the following MSDE 2000 registry keys:
1. For an MSDE 2000 default instance, remove the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer
2. For an MSDE 2000 named instance, remove the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\<INSTANCENAME>
3. If the following registry key points to the MSDE 2000 instance ProductCode, remove the value InstanceComponentSet.x. For example, InstanceComponentSet.1 has a value that matches the ProductCode of Sqlrun01.msi:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Component Set\InstanceComponentSet.1
4. Remove the SQLServer Service registry key.
For an MSDE 2000 default instance, remove the following:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQLServer
For an MSDE 2000 named instance, remove the following:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQL$<INSTANCENAME>
5. Remove the SQLServerAgent Service registry key:
