The disk is not running on my computer, it says it's a 16 and I have a 64bits? What does it mean?
This is an error caused by the fact that, when running in Long Mode, x64 native, your CPU doesn't support going into 16-bit mode. So, in order to install and use your 16-bit application, you will have to use an emulator, such as DOSBOX. Go to http://dosbox.software.informer.com/ for more information about it.
