i discover that is an International issue.
if system language is English, AU works fine, but if system language is my local, AU can't find "executable" in </Library> (boot volume /Library [folder]) cos it's no /"Library" anymore. now it's just /"Ĺïßřäŕŷ" in my local transcription, but other AU's (Apple & 3rd party) have an immunity from this.
it is possible to fix this international incompatibles? how?
