I have recently uninstall Norton Utilities from my computer because I would manually install Vista Service Pack 2 Standalone Package. Windows Update would not update because of an error number 0x80070002 and Microsoft Windows Readiness Tool cannot fix the problem. After the install of Service Pack 2(in safe mode) (All Norton Products had been uninstalled before the installation because it can conflict the installation) SP2 Standalone Package asked me to restart my computer to rollback the installation because the installation fails.(I do not know why??) After booting, windows cannot start. So I used System Restore to fix the problem.
ALL OF A SUDDEN, ALL NORTON PRODUCTS THAT I UNINSTALLED AND ALL THIRD PARTY SOFTWARE CAME BACK.
Norton Utilities was only affected. Its uninstallation files was not found. So I cannot uninstall Norton Utilities. I have tried NRT but it DID NOT WORK. Control Panel uninstallation the same failed. I would reinstall Norton Utilities also because it cannot load its main components. Norton AntiVirus,DNS,Safe Web Lite were not affected. Their main Drivers loaded properly.
