The terms "32-bit" and "64-bit" refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system.

The basic difference between 32-bit and 64-bit operating systems is the number of calculations per second they can perform, which affects the speed at which they can complete tasks.

The majority of personal computers now use 64-bit, and 64-bit processors are likely to become common in mobile devices.

You will be able to install the 32-bit installation file on a 32- and 64-bit operating system, where you will not be able to install a64-bit installation file on a32-bit operating system. 

As from Release 6.1a, there are two installation files to select:

• 32-bit installation file
• 64-bit installation file
