Hi, the last line of the install-tl-advanced.bat file included in install-tl.zip (Installing TeX Live over the Internet for Windows) is: call "%~dp0install-tl.bat" -gui perltk%* but the correct way is: call "%~dp0install-tl" -gui perltk%* Otherwise the expert installation is impossible. Please, correct this. Thanks. Jerónimo Leal
