A. A. If the standard un-install utility doesn't do the trick for some
reason :-
Remove the <sql> directory and everything under it
Remove the <sql> dir from the path (use control panel/system for this)
Remove the SQL registry entries using regedt32/regedit. These are :-
(All versions)
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQLServer
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer
(6.0 and above.)
- HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSDTC
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SQLExecutive
(7.0 and above)
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SQLServerAgent
- HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft SQL Server 7
- HKEY_LOCAL_MACHINE\Software\Microsoft\MSSQLServ65
If you have lost permission to any of the registry keys then log on as
administrator and take ownership of them starting at the highest relevant
level. Use regedt32 and check the box to take ownership of all subkeys as well.
