I bought a copy of after effects 5.5 for mac (OS X Yosemite) and when I click on the red "Install" icon, a window that says "Initializing Installer" appears. There's a loading bar at the bottom of the "Initializing Installer" window and after the bar has filled (done loading), the window disappears and nothing happens after that. How do I fix this?
Are you talking AE 5.5 or AE CS 5.5? 5.5 came out in 2002 and will not run on Yosemite. If it's CS 5.5 then these are the requirements:
Make sure you have the latest installer. Yosemite is OS X 10.10 an that's a long way from 10.6. You may be in trouble. CS5.5 was released in 2011 and 10.6 was in 2004
