I had been trying off-and-on to install a more recent version of Flash Player on my Mac (OS X 10.8.4) for several weeks. I am using Safari and Chrome browsers, but neither of them were running during installation. The problem is that it always gave a message asking that DashboardClient be stopped, but the installer provided no suggestions on how to do this, and the document at http://helpx.adobe.com/flash-player/kb/installation-problems-flash-pla yer-mac.html doesn't cover the situation.
I read in several threads here that the fix was to start Activity Monitor and to kill DashboardClient. The first problem with this advice is that "DashboardClient" isn't listed as a running task in Activity Monitor, although "Dashboard" is. The second problem is that on this system there are three instances of Dashboard listed under Dock, and killing any of them immediately results in a new instance.
What finally worked was killing Dock itself, then immediately clicking on Retry in the Flash Player installer. I did miss the live presentation I was trying to watch, but the new version is installed.
Could some help on what to do when a user gets the message about DashboardClient be added to the Mac version of the Flash Player installation problems document? Thanks.
