Norton 360 can't install - MS KB4474419 security patch problem
al corriente: 05-Feb-2022 | 11:55AM · 10 Respuestas · Enlace permanente · Translation:
In the morning of 2/2/2022 Norton 360 failed an update and corrupted file symefasi64.sys, which prevented Windows from starting.
Once I managed to boot my computer I uninstalled Norton 360 and attempted reinstall. However the install failed because it required a MS security patch KB4474419 for Windows 7 32 bit. I followed the link provided and attempted to install the security patch, but it stopped with the message "The update is not applicable to your computer". How do I force the Norton install to stop messing about, and complete? The only options offered are close or install a security patch that won't install and is not meant for my computer.

Yes, but my extra problem was that I can't install the Microsoft security patches. So the sequence of problems and solutions for me were:
Problem 1: Computer fails to start Windows because ...\symefasi64.sys was corrupt. My computer is old with Windows 7 Home Premium.
Solution step 1: Press F8 during startup and select "Last Known Good Configuration" from the boot menu. Press enter. Windows should restart normally.
Solution step 2: Uninstall Norton 360 using the uninstall and reinstall tool from the Norton site. Windows uninstall can't uninstall Norton.
Problem 2: Reinstallation failed because I did not have the Microsoft security patch KB4474419.
Solution step 3: KB4474419 is available from the Microsoft update site. If you can download and install you can complete the Norton reinstallation.
Problem 3: Installation of KB447419 fails with the message "The update is not applicable to your computer"
Solution step 4: Go to Norton support chat. Eventually they can provide a download that will install on Windows 7 without requiring KB4474419. It may take an hour. You will need to be able to sign into your Norton account without using automatic password completion. I advise against trying to find the download elsewhere, because you won't have protection and sites offering the download may be dangerous.
