Fyi, I have reported the exact same problem some weeks ago:
I guess it has something to do with us running a french Mac OS...
After many re-installs, I gave up and successfully installed it on my (english) Windows XP system.
If only we had the option to install Catalyst in english, this might solve or problem (or not).
Thanks to you David, I found the solution!
In fact, I created a new account in which I changed the main language (into the International preferences panel).
It is really curious, because then, certain folders pass in English, and others not. And AFC works!
I note that if I change the language on my main account, it doesn't work.
AFC certainly has to create files in the first opening in an 'English environment'.
Well, Thank YOU Olivier for finding this workaraound.
I was able to do the same, which is far from perfect but is still a great improvement over the previous situation.
Note that I didn't try to switch the language on my main account. You say that didn't work, but maybe it just needs to reinstall Catalyst ?
Yes you're right! I thought on it later… But it doesn't work all the same. Certainly Catalyst needs some system files in english version (these which don't change by the language panel), and i do not want to reinstall the system. Then, i have two accounts, one french, one Catalyst!
Expecting a new release…
Thank you again!
