Hallo,
i'm on Windows7 32bit (de-de) with Audition 3.0.1 and language strings are mixed up ('de-de' and 'en-us'). I installed audition with 'english' language (clean 1st time install) and 'HKLM\SOFTWARE\Adobe\Audition\3.0\Prefs\Language' is '0'. I also tried to remove 'de-de' folder but doesn't help. The corresponding files like 'Nonoise.xfm' are multilanguage (holding multi5 unicode strings) controlled by the host software (Audition) so its not possible to just remove locale files to force en-us output.
I'm currently out of ideas. If you know some tricks to force 'en-us' on a localized system please leave a message.
Thank you.
