look in the folder that saved on your comp, then click the "Read Me" file it's a click and drag installation. At least for a mac it is, pretty sure the same for PC
dude the second level macbook comes with GL 1.2, whatever the fuck that means, but thats what it said in the log that the readme document told me to read. Anyways, since you need a GL 1.5, if wont work with a macbook
