no
64 or 32 although the 64 will be able to run 32 bit programs.
Programs written for 32-bit operating systems will run perfectly well on a 64-bit system.
In simple terms, 32-bit operating systems can only be able to run on 32-bit CPUs and 32-bit apps, but a 64-bit operating system can be able to run both 32-bit and 64-bit CPUs and apps.
You don't have to "do" anything. All general-purpose 64-bit operating systems will run 32-bit applications as well out of the box.
No.
Most 64-bit operating systems contain a 32-bit translation layer. Installing a 32-bit program is no different than installing a 64-bit one.
No special action is needed. 32-bit applications are run transparently.
You mean 32-bit and 64-bit, not 32 byte and 64 byte. A byte is an aggregate of (usually) 8 bits. 32-bit programs will execute in a 64-bit environment without any modification. 64-bit programs can also execute in a 32-bit environment, but this requires emulation through a 64-bit virtual machine.
Yes.
if 2k9 has a 64-bit installer - then it's yes or you might have 64-bit processor, but using a 32-bit OS (e.g xp 32-bit, or vista 32-bit) - then it is still possible.. hth rj
The R3000 only has a 32-bit processor; it cannot run 64-bit software.
No you can't because 64-bit won't run on an x86 (32-bit) PC. You have to have the x86 version.
