I am really hoping someone can help me with this. I bought Windows 7 Professional (full version) from the online Microsoft store because of the student discount. But instead of receiving a disk, I had to download 3 files onto my Macbook. [setup1.box, setup2.box, and Win7-P-Retail-en-us-x86.exe] When I open Parallels, it asks me to insert a disk. What can I do? I have already talked to technical support from Microsoft and Apple and they have been no help. This is my last hope.
