this is probably a seriously dumb question- I apologize. I have Adobe Design Premium CS5. Obviously the retina doesn't have a CD drive, so now I'm at a loss as to how to get the software on my retina- I don't want to buy a superdrive for this ONE thing- it seems like there has to be a way of getting it on here without it. A friend told me I could use my old MBP's disc drive somehow, but my 2008 MBP's disc drive has been dead for like 2 years. I contacted Adobe support and they won't offer me a download, even though I have my serial number. I just tried putting it on my external hard drive (just a simple copy/paste of Photoshop alone to test) but when I try to open up Photoshop I get an "Error: 6" message before I can do anything. This is a totally legal purchase- I have my serial number and everything...I just can't figure out how to get CS5 on the retina, because all of the trial downloads on Adobe's site are for CS6. Another friend suggested I download a torrent or whatever, but I want to stay as legal/safe as possible. Surely someone else has run into this problem, right? Any ways of getting the software on the new computer without springing for a drive? I could always buy the drive, use it, and then return it, but I'd really like to get this software on here tonight...I'd much rather work on homework on my speedy new retina than my old mbp!! sorry for the ramble! tl;dr: how can i put my (legal) copy of adobe cs5 software on my retina WITHOUT using a superdrive. Are there downloads? Will an external hard drive work?
