This is a minor bug. I launched ASF V3.0.4.3 on Windows and I saw this message:
2017-11-03 13:02:14|dotnet-5068|INFO|ASF|InitGlobalConfigAndLanguage() ASF will attempt to use your preferred pt-BR culture, but translation in that language was completed only in 99,4%. Perhaps you could help us improve ASF translation for your language?
However, the only thing in pt-BR in my OS is one of my keyboard layouts. The language of the OS itself is en-US, that's why ASF actually display all logging messages in English.

That message shouldn't be shown.
I get a message about my OS language, which is incorrect.
Maybe add a secondary keyboard layout and simply open ASF to get that message?

Good catch, thanks, you can check if latest AppVeyor build addresses this properly.
Working as expected now, thanks!
