The naughty 5 should be emphasised.
What is the best way to see if you have the most current versions?
Most of them have an option (which defaults to on) to check and see if there’s a more current version. So start ‘em up, make sure that option is on, and give them a few minutes to phone home, and watch for little things in your tray, Adobe is really fond of the nearly silent download, so if you just whip open a PDF and close it two minutes later you could be interrupting an update.
