Windows 8 is telling me that I don't have a 64-bit processor, but I do (my Macbook is a 2010 model, all of which come with 64-bit processor).
"This 64-bit application couldn't load because your PC doesn't have a 64-bit processor. ... Error code 0xc000035a"
Also, I have enabled PAE/NX in VirtualBox. Any idea what the problem could be?
