I am trying to become a new user of Parallels. I want to run Windows on my Macbook. Unfortunately, time is of the essence and the convenience store has been down for days. From what I can tell, the convenience store is where you go to buy Windows. Is there any other way to buy and install Windows on my Mac so that it will work with Parallels? Or, what's a good alternative to Parallels--kind of a put off that the convenience store has been down for so many days. Thanks.
