I wish I had read this post before reinstalling an English CS4 trial version just to make the Gaia panel work.
I did find an alternative solution though, now that I had to reinstall the French CS4 version:
(ok, don't get me started on language specific Adobe licenses)
On MacOS X, I simply changed my operating system language to French (same as my CS4 license) before installing the Gaia Framework.3.1.2.mxp, and TADAAA it installed correctly, it showed up in the "Autres panneaux"="Other Panels" menu, and it works perfectly.
It even keeps working now that I switched MacOS X back to English.
Now I just have to get my CS4 license converted to English, so that I can stop reinstalling and start coding happily
