Cannot choose destination selection.
OS: Snow Leopard 10.6.8
Installing a demo version of Mixmeister, after agreeing with the licence ("Licença" in the image), comes destination selection asking "Where do you want to install this software?" showing only the option "Install for all users in this Computer" but this is freezed out and the button "continue" too, greyed out. It's the first time it happens and I can install other software with no problem. Isn't it strange? Please help! Thank you.
