Hi again, Rado! I try to do this, what you've wrote, but I failed. I've extracted files and put them in selfextracting file with winrar, but don't know what path to put for the selfextracting archive. Would you help me. And I don't know how to pack file like addon. What mean this? Because nlite works with .exe files and sfx file is .exe. Sorry for my ignorance. I'm layman as you see.
