I over installed from 4.0.314 on two W2k8 Servers, one an AD server with minor issues only. Several machines in this network have failed to load realtime monitoring on reboot sunce updating to v4 and windows vista/2k8 SP2 The third server a w2k8 SP2 virtual Hyper-V AD Domain Controller failed to Update. It advised it would install after reboot. Since then I have tried everything including an msconfig basic services start to get it to fully uninstall 314 by re-installing it - to no avail. The upgrade uninstall failed to remove the server services and they are still running, and cannot be altered and the files are locked. choosing a reboot install prompts initially "Installer has insufficient privileges to Modify this file:c:\...\x86\msccp80.dll" - permissions on the folder and files eem fine. UAC is off Clicking through ignore finally moves to Registry access issues and finally fails to uninstall the service. is there a manual uninstall process, how does one get around the service being protected, is that appropriate on a forum??
