I'm computer illiterate, so I hope 1 of you can provide me some simple instructions for installing Windows 7 on my macbook pro. I don't have a Windows 7 CD, all I have is a file called "DLMWin7HP64US.exe." I double clicked on it and it opened up with "TextEdit." I tried running the Boot Camp application and it said I needed a Windows 7 CD. Did I buy the wrong thing? How can I install this .exe file on my computer? I hope I didn't waste $29.99!!
