Bump. Is there really no one who knows this? Thank you.
It appears that you exceed the HIPS hardware requirements, so that should not be the issue. There are certainly newer versions that your corporate IT staff should be able to provide, if they have a valid license. You might want to point them to the installation log located in the Windows directory named McAfeeHip7_Install.log as I gather the root cause could be determined by reviewing this file. Your administrators should be able to review this log (or open a case with McAfee for support) and correct this problem.
Also, when you say that you removed and reinstalled HIPS, you did not mention how that was performed. What software installation package did you use? This certainly does matter as you will need to obtain that latest package from your IT staff to assure proper installation can be performed.
Hope this points you in the right direction.
