PPCC and AE only run on a 64 bits machine.
Is yours 64 bits?
Ok that explains it have 32 bit win 7,will I be able to install on my
MacBook Pro? Or is license only per CPU?
I'm not sure what you mean by "is the license per CPU." Did you mean per OS platform? Anyway, the license is very flexible. Unlike prior perpetual license versions, which were platform-specific, CC allows you to install on both Mac and Windows. I'm not sure whether it specifies how many computers you can install CC applications on, but you can have it activated on only two systems at once.
