I desparately need to run Revit for school, and cannot afford to buy a new laptop. The tech specialists at my school have no clue what to do. I tried calling Revit at every single one of their locations and every time I was asked to leave a message because no one could answer the phone. Everyone I've talked to has no clue what to do. It's really frustrating because I'm positive that bootcamp and Windows 7 were installed correctly, and that I have enough space on the partition to run Revit, it just simply won't work. This time rather than not working from the start, it downloaded completely and then at the end it said 'error: the opperating system is not supported' and it stopped working. I paid $50 for a professional to bootcamp my Mac for me, and he said it was challenging even for him to figure out even though he is certified in Mac technology. Revit would not download, so I decided to be done with parallels and just try bootcamp. Both were installed perfectly because I had a tech support guy make sure I did it properly. At first I wanted Parallels because it is more convenient than bootcamp, but after purchasing both parallels and Windows 7, 64 bit, Revit would not download. I'm running OS X El Capitan, Version 10.11.3. I'm about to have a mental breakdown because I've tried everything under the sun to get Revit on my MacBook Pro 13', not retina display.
