When I try to install the upgrade to 14.5.1 it ask me to quit the Sync Services Agent and the Database Daemon. 

However if I go to the Activity Monitor and force quit these they will not quit no matter what I do.

So, I can't move forward to install 14.5.1 .

Any ideas or help in forcing these to quit so that I can install.

I am running OS X  Yosemite 10.10.3
