I would like to know the following things :
- Can a 32 bit application run under a 32-bit operating system?
- Can a 32 bit application run under a 64-bit operating system?
- Can a 64 bit application run under a 32-bit operating system?
- Can a 64 bit application run under a 64-bit operating system?
Thank you.
