I install manually McAfee HIPS on XP sp3 without problem.
Everybody well knows the difficulties to unstall it.
It seems to have several solution to do that. - Directly from EPO (but for an manual uninstall, is not the solution) - By unlock interface then disable IPS/NIPS then uninstall from add/remove program or by msi command - using clientcontrol.exe, with 'clientcontrol.exe /stop <password>' to stop HIPS then you can uninstall it from add/remove program or by msi command
But i discover recently a new possibility : At the same foler where clientcontrol is copied, an other tool is copied too : InsFireTdi.exe. When you execute it, McAfeeHIPS is completly remove without define password (a good news !!) but I don't find any information about this tool. Someone know exactly what this tool do ?
I've just tested again to uninstall HIPS using InsFireTdi.exe but now it doens't work anymore. May be I tested 2 methods in the same time to uninstall HIPS and I have believed that using InsFireTdi.exe had worked
