Re: Flex Installer Issue -- invalid file?
Thanks Alex. Flushing cache in Safari did the trick.
(If you're a Mac OS user and need a reminder, like I did, on how to flush
Safari's cache: you enable the "Develop" menu in Safari by selecting "Show
Develop menu in menu bar" checkbox on Safari > Preferences > Advanced, and
then select Develop > Empty Caches)
