This ceased to be installed after 9.2 I'm afraid. Oracle 10g installed differently o n Windows and I seem to remember having to run the installer each time I wanted to change the version of client I needed to use. It was working perfectly until 10g came along, but then Oracle changed it - and basically removed the Windows equivalent of "oraenv" so loved by us Unix bods. A retrograde step in my (occasionally humble) opinion!
