Hi orlando357 and welcome to the community
Are you getting any specific errors when you try to install AutoCAD? Any details or additional information you can provide us with will be very helpful!
I have a Macbookpro and installed parallels& windows 8.1, in order to be able to download and run Autocad, which i have registered for through a student version 3 yr trial.
I am having issues downloading cant figure out why as everything seem to be in order sys requirements etc
will be grateful for any assistance with this
