Current version of VSE is 8.8 patch 3.
8.5i is no longer supported since Dec 31, 2011 (2012 for Windows 2000 users). See: https://kc.mcafee.com/corporate/index?page=content&id=KB69579
Whomever or wherever you got this from I don't know but Enterprise comes in bulk licensing format only (a company or institute must purchase multiple licenses) and you should uninstall this version completely. Ask your source for an upgrade to a current product or use another security software, maybe a consumer product that allows individual licensing.
8.5i is no longer protecting you. End of support means we can't help you here with any issues regarding that version.
Uninstall it in the normal way. If you have difficulties see: https://kc.mcafee.com/corporate/index?page=content&id=KB50602
Thanx for the reply
Good luck ;-)
