I am trying to remove HIPS from an XP workstation via ePO 4.0 and it will not remove. I viewed the cmdagent log and in says the it had been removed. I can change from HIPS 7. to ver 6 successfully. I remoted into the machine and there is nothing in the HIPS activity log. I have un/reinstalled framepkg and McAfee 8.7 and still appears that is is there. I see the Hips sheild on the desktop and ePO is reporting it is still installed. Went to add/remove programs and don't see it there either.
You could check and see if the following registry key is still present:
If it is, copy the UninstallString value into Run.
If this does not work, you'll have to refer to thee HIP 7 manual uninstall doc.
If this is consistently reproducable, I would open a support ticket with McAfee support.
