Uninstalling Internet Explorer?

I installed IE 5 - my preferred browser - but the install crashed at the last moment.

IE 5 is not functioning mostly correct, but there are a couple of small but annoying issues.

How can I remove IE 5 so that I can reinstall it properly?

Attempts to reinstall from disc have not worked - it thinks IE is there and fine - and removing the IE folder from “program files” simply cripples many applications.

OS is Win98SE. Any comments much appreciated.
