I am asked to turn off Safari(v7) for the Flash Update even when Safari is not on.

I have tried many times to install the Flash update on my MAC (OS X 10.9).  It asks me to close Safari to finish, even when Safari is not on.  I even restarted the computer, never opened Safari and it still asked me to close Safari.

If you use MenuTab (Facebook plugin), it will give a false "open" for Safari. It sets as a Login item by default when installed so rebooting won't help.

Applications/Utiltites>Activity Monitor.
Terminate MenuTab, and proceed with the nstallation.
