Microsoft VM not present

ok heres my question, Im working on a machine that was having problems with certain java applications,I found out that the microsoft vm under tools in IE is missing.also there was no IE in add or remove programs so i just did a search and deleted everything i found for IE.
I then installed a new copy of internet explorer 6.0 only to find out that there still is no microsoft vm present. this is on windows xp what could be causing this and how do i remedy it?
