Why .com file doesn't work on win 7 x64?

Question

Windows

I understand that the bit depth of the OS is different, that there is WoW64, but where can I read more specifically or what am I missing?
Well, for example, we have a .com file, the content is as follows:
B4 02 B2 41 CD 21 CD 20 C3
It works under x32, of course not with x64. But what needs to be done?

Answer 1

if I'm not mistaken, then com is a 16-bit program, and 64-bit windows do not support them, in principle
, use an emulator with dos

Answer 2

Dos box to help you
