What is com.apple.WebKit.Plugin.64 and how do I close it to install Flash Player?

[blsdwm3]

I am trying to update my Flash Player.  During the install process it says I need to close the following program:  com.apple.WebKit.Plugin.64  I have no idea what this is or how to close it.  I am running Safari 8.0.2 in OS X Yosemite.  Any help would be appreciated.  Thanks!

i too was trying to update adobe and it kept stopping, saying i needed to close

com.apple.webkit.plugin.64. but i had no idea where that was.  so i opened the activity monitor and found it.  it said it was opened in safari, under our guest account.  i had closed safari under my user name, but didn't realize it was still opened under our guest acct.  once i closed it there, i retried the installation, and i am happy to report it finished it with ease.

so i would say to try and make sure safari is closed for all account users using your computer!!

good luck!!

The old addage "when in doubt, reboot" is still pretty solid advice as well.
