1. Delete the following directories and their contents.

   After you have deleted the key, exit regedit.

More Information About DaFIS TP Uninstall

Only the Oracle Net8 Client portion of DaFIS TP is installed on your computer. The Compuware Uniface portion is stored on the Q: drive.

When we say uninstall DaFIS TP, we really mean uninstall Oracle Net8. That is why all of the uninstall instructions refer to Oracle products.

Most Windows applications can be removed via the Add/Remove Programs control panel. However you won't find an entry for the Oracle Net8 Client in the Add/Remove Programs control panel. Oracle provides an installer utility instead; in normal situations, you can use the Oracle Universal Installer to add and remove Oracle components.

There are times when the Oracle Universal Installer is not sufficient for uninstall needs. For example, it may not recognize all of the installed components, it may not be able to uninstall old versions of Oracle components or it may crash when you try to run it. In these situations, the expert uninstall method is the only alternative.
