Hi, I'm trying to install vmware on my MacBook Air through a LEGAL dvd I downloaded in MSDNA program (university program).
It ask for drives of optical unit but in MBA there's no optical unit!!
Did you check 'Use Easy Install' when you began the installation in Fusion?
I have the same problem as the original poster. You can't pick Easy Install because that only seems to work when you have a CD attached. With the MacBook Air, you have to initialize the VM with the Win7 installation disk.
On a MacBook Air without a SuperDive attached you need to use an ISO Image to install Windows in the Virtual Machine.
