To clarify you have the
Key - HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Version Vector but no IE value?
This key should be set by IE when it was installed.
A fix to your problem you could add a string value called IE with the value of 6.0.
I have some questions to understand how the machine got into this state -
1. How was IE installed on this machine? Windows update, IE CD?,
2. Was this machine upgraded from previous version of windows? I found a post on MSDN stated that there is an IE bug - if the machine was upgraded from Win98 this key will not be set.
3. A screen shot of IE's about box
4. Was there anything different about how your machine was setup? Was it a clean XP SP2 install? factory installed? etc
