Remove an Old Version
Before installing the new version of Oracle, you must remove the old one. The following procedure deinstalls the entire Oracle database.
- Select Universal
Installer from the menu path Start
Programs
Oracle - OraDb10g_home1
Oracle Installation Products.
- In the installer window click Deinstall Products. Make the appropriate selections in the dialog boxes.
- In the installer window click Cancel.
- Delete or remove the Oracle folder from the file system. This folder will be recreated when you install the new version of Oracle. You may encounter a permission problem when you attempt to do this. In one case the problem was that an Oracle DLL was still in use; a restart fixed this problem.
