Add/Remove programs doesn't work in 2K.. can I reinstall just this part of the OS?

[DriveX]

I get this error message when I try to use add/remove programs:

Object doesnt support this property or method.
res://appwiz.cpl/default.hta
Line: 75

Can I reinstall just that part of the OS without formatting or reinstalling 2K?

If the Add/Remove Programs applet is not working, this is a symptom of a corrupted upgrade to IE5.5 or IE6.

To correct the problem, simply reinstall IE.
