I'm sorry: And how to use it on TLauncher? In my chat, instead of the skin, Steve.

P.s Maybe this is not the right place for the question, I apologize. I tried to ask on Sourseforge, my message got into spam. And I also do not know where to write, I do not understand English well, I write through a Translator.

Please don't use TLauncher.

TLauncher is closed source, so we can't fix any issues with it.
TLauncher is also illegal, so we won't fix any issues with it.
