After my first initial success with installing Adobe Connect (per asince's post), I've had mixed results. I've reinstalled in a couple times, possibly following Flash updates, but I'm not sure. I've also found that sometimes I need to clear my browser cache, relaunch the browser, and then it works. I've also tried restarting the computer entirely, but the cache and app relaunch seem to be the key steps.
That said, this solution has worked but with lots of hick-ups and inconsistency. If you NEED to have a solution, try a browser cache clearing, browser relaunch, possibly a restart, and reinstalling Adobe Connect. Waving a rubber chicken wouldn't hurt, either.
