tryna download battery on my macbookpro

hello all i just brought battery and im trying to download it on my macbookpro when i start my computer and click on the macintosh hd icon its says i have 79gb available, but for some reason when i insert my battery cd it then says i have zero kb available anyone familar what could be causing that?

furthermore when i start the download it stop halfway and say i need to select a drive with approx 11gb free.....im confused because my harddrive barely has anything on it with 79gb free

I'm confused as well - what battery CD and what is it supposed to do?

WOW...I'm very very confused!

I'm pretty sure he means Native Instruments Battery, it is a drum VST used for DAW's like Fruity Loops, Reason, or even Logic.
