I know the option exists to use the built in updater in system preferences.
But in cases you have multiple macs to update, it's sometimes easier to just download the updater, put it onto a thumb drive, and then manually install in each mac. My question is this:
Do I need to first untinstall the previous version via the uninstaller app in the utilities folder before installing the new version? Or can I just run the new installer without deleting the old one. NOTE: the "old" one in this case is usually just the previous version of Flash Player released.
