Mac OS 10.7 (Lion) won't start After Effects CS5.5 because it's a powerpc app!?

Tags: #lion #mac #after_effects #cs5.5 #os_10.7

I've had CS 5.5 Master Collection installed on my Mac since it came out. All the CS 5/5.5 apps I've used up to now have worked fine, in 64-bit mode (Photoshop, Illustrator, Acrobat Pro, InDesign). Now I need to use After Effects, but I can't get it to start.

First it said it couldn't rename a Workspaces.xml file in the preferences directory in my home folder. In fact, there was no such file there at all. Nothing to rename. So, I uninstalled After Effects using its uninstaller; then reinstalled it from the install DVDs.

Now, it fails on startup saying the After Effects CS5.5 application cannot be run because PowerPC apps are no longer supported. True: OS X no longer runs apps that require Rosetta. CS 5.5 is does not require Rosetta; it's compatible with Lion. The OS 10.7 Known Issues KB article says nothing about After Effects: http://kb2.adobe.com/cps/905/cpsid_90508.html?promoid=JBQYY

So...what's going on? I need this thing working for a project with a deadline! I don't get it. Anybody seen this before? (I didn't find anything in the discussions about it, nor Google...)

Did you do any updates of the OS between this and the last time you used AE?
Sounds like a simple prefs issue but I've never seen this parcualr issue so You might search for a broader collection of statup issues.
Locate your AE prefs and trash 'em. There are several threads on how to do that around here, strongly urge you to search them down before you just plow into your library and start throwing away Adobe-labled app support and .plist files.

You may also find additional advice on apple.com's discussion forums.

Also, give the forum a few more hours, if you can, to see if the power wonks offer better advice.

Interesting article, but I knew I was leaving PowerPC apps behind when I moved to OS 10.7, and Adobe claims that After Effects CS 5.5 is fully compatible with Lion. But you must be right about prefs; there's gotta be something causing the Mac OS to think this version of CS is ancient...

Since my initial message, I've tried and failed to find any details about how to select the right prefs to delete. I also ran Disk Utility to repair permissions on my system drive. That got rid of the PowerPC error:) Now on startup AE says mediacore fails to initialize. I can choose to quit or continue on that error, but continuing just results in another error that says dynamiclinkmanager unexpectedly quit, and then AE locks up and I have to force quit it. Not much progress!

No other answers on this so far... Before I uninstall the entire Creative Suite and then delete all Adobe system and hidden files everywhere, any more suggestions? Or a list of the right prefs I should trash?
