Hi so I have an Intel MacBook Pro partitioned with Leopard and Vista (i purely use Vista for gaming) and just tried to download the Photoshop CS4 trial because I'm tired of using GIMP and I get an error that says something along the lines of "Can't install on this volume. Must be writable, local, and (something I can't remember, don't feel like d/l'ing again)." Also along these lines if I try to stick files from Leopard onto Vista it says that only administrator's can do that. I know that I am the admin because I'm the only profile on this, and it lets me install stuff on Leopard that you have to be the admin to do. My friend says that you can trick it into making dual admins, but it's kinda complicated. Any help would be appreciated. (Also I've run the CS3 trial on Vista, so it isn't the MacBook itself).
