Currently I have Lion installed on both my macbook (was originally Leopard, have updated upon release to both SL and Lion) as well as my iMac which came pre-installed with Lion. Because I downloaded Lion on my macbook I have the file in my purchased section in the mac app store. What I'm trying to do is get lion for my girlfriend. I know apple has it in place that you can install Lion on more than one machine but does that only work for one iTunes account? I tried logging into my account on her macbook pro and I got it downloading but when it finished (several hours later) it said it couldn't download or something. I'm not sure of the exact message as I was out of the room but that's what she said. Was this an error or a usual thing? Because it wasn't originally downloaded on that mac can she not get Lion from my account? Would it work if I re-download it and then transfer the install file to her? Or will she just have to pay for it herself?
