The short answer is yes. However, there are more factors at play rather than whether your PC is 32 or 64 bit. If your processor only has 32-bit it might not have the required NX bit, which is a minimum requirement for Windows 8. To ensure compatibility with Windows 8, you can check your PC's compatibility with the Upgrade Assistant (http://go.microsoft.com/fwlink/p/?linkid=261871).
