You cannot (normally) run 64 bit programs on a 32 bit OS. Is there a way of running a 圆4 bit program on a x32 bit system? The documentation for that can be found here. It is just the one I first rememberedĪs pointed out by Ismael Miguel: As long as your hardware is 64 bit you can use VirtualBox to run a 64 bit OS. You can not change the windows OS from 32 bit to 64 bit. Note that this means a full reinstallation. DavidPostill's answer is extremely complete on that.
If your computer has 64 bit hardware (basically everything from the last decade) then you can install a 64 bit OS. Or is there a way of upgrading from x32 bit to 圆4 bit for free. So, as an answer to part 1: Technically yes. Now if you are going to emulate then expect numbers to be the other way around.(Long long ago I tested and reached 99% speed of the host using vmware workstation 5 and dnetc, which is a typical user space program.) Running a hypervisor to run a 32 bit VM on a 64 bit host will let most programs run at almost full speed.However this will come with a significant speed loss. You can use Qemu or a similar emulator to emulate a complete 64 bit host.
