Is there Greek Language pack for CALCULUX previous to version 7.7?
As I can see, this question has been addressed before and you are the author of the comment on the developer's page. I have double checked, but the developer didn't release anything about Greek language support for this application. I recommend insisting with the comment on the same page because that's the only way and place you'll get answers.
