Invalid ActiveX/COM files

I have a Dell PC, and purchased it with Windows ME
installed. I purchased Norton SystemWorks 2002 for the
system.

I then purchased Windows XP Professional. The Norton
SystemsWoorks was not compatible, so I run it from the CD.

The problem is that I cannot fix the problems with the
ActiveX/com files. I run the Win Doctor every day or so,
and the same 23 problems return.

What can I do to fix the problem?

Thanks for your assistance.
