The Nuts: (Un)Deinstalling the Oracle Client

Frankly, I dislike Java-based installers as they tend not to tie in well with the Windows operating system, and the Oracle client installer is no exception.

This 2-part post will help avoid these situations before they begin or help rectify them if you already find yourself in a bad spot.
