It's a configuration issue on your system that exposes itself in Outlook.
To repair:
In Vista; Start-> Default Programs; reset Internet Explorer Defaults
In XP: Control Panel-> Set Program Access and Defaults-> Non-Microsoft->
Default Web Browser-> Internet Explorer
If that doesn't work and the pop-up comes up point it to IEXPLORE.EXE

When I go to Start>Settings>Control Panel I do not see a Set Program Access
and Defaults link. Where will I find it?

Sorry, double click Add/Remove Programs to see that section.
You can directly find it in your Start Menu as well (listed under Control
Panel).
