I recently installed the Hips 8 P8 patch to epo and most of my machines successfully updated. However, a few of them are giving me trouble. First they continually run an update task and then ask to reboot. HIPS no longer shows up under 'manage features'. Uninstall jobs from epo also fail.
There is no silver bullet here. Sounds like something happened during the upgrades that left HIPS in a partially installed state. I'd suggest attempting to uninstall locally and see what happens, otherwise, you'll need to contact support for assistance. Support can help troubleshoot and if necessary provide a ripper tool to cleanup the remnants and get you back to a state where HIPS can be reinstalled.
