Hello,
I have IE installed on mu PC running on windows 2000 but it does not open.
I thought let me remove IE and re-install but I am unable to see ADD/Remove programs on the control panel.
Any idea what is the problem. I can open Yahoo messenger and msn messenger.

Hard to say without more detail. Sounds like it could be virus related though.

Try Bob Cerelli's Windows Site for Internet Explorer tips and fixes.

Best wishes,
Nez.
