Grapher installs and runs correctly on 32-bit and 64-bit versions of Windows operating systems. Grapher has both a 32-bit and a 64-bit version included in the installation. The installer will automatically select 32-bit on a 32-bit system and 64-bit on a 64-bit system. On 64-bit systems, you can select whether to run the 32-bit or 64-bit version when installing.
