Hello,
Whenever you are installing updates, you should always disable Anti-Virus and any other program currently running.
Anti-Virus programs can misinterpret updates as unauthorized modifications. If they do, then they may prevent something from being changed that should be changed.
Likewise, some programs can cause trouble by just being open. If they are actively calling on a routine when that routine gets updated, then you could have a problem.
So, before you install any update, close and shutdown any program that is running.
I personally will usually shutdown and restart right before an update. That way I know everything is definitely closed. But, you will need to disable / close some programs (like Antivirus and Security programs) manually. Even after a restart (unless it has been set to prevent loading at startup).
I hope this helps.
