Install button - nothing happens
I've just upgraded my OS to Snow Leopard, and I deeply regret it. I'm trying to install some stuff such as MySQL 5, which some sites say it's compatible, but just as like other softwares, it displays the Installation Window, but when I press the install button nothing happens.
Any ideas why it's happening?
PS: I want my money back!!!
