I've quickly read the first message of the thread and sorry but this will not be done. I've already often talked about internet download during the setup and I'm absolutely against it, for many reasons. I want to let people share Messenger Plus!, backup their favorite version on a CD, etc... my setup is one big chunk of program, everything is included in it, and it will stay that way.
As for updating the language automatically, it's actually a bad idea. That's how softwares like Linux get so messy. You need some people to control what's going on, or else,everything becomes chaotic. There's already a Language forum where peopel can post updates, then I can make the change once approved and the new translation file is released with the next version of Messenger Plus!. It may seem to be a little tedious but that way, everything keeps working fine and there's no risk that a lkanguage file become so bad that it has to be recreated from the beginning.
I hope I'm clear lol, I gotta go, sorry
