Knowing if your copy of Windows is 32-bit or 64-bit becomes very important when installing device drivers for your hardware and choosing between certain kinds of software.

The 488.2V4 GPIB driver for controlling test instruments fully supports 32- and 64-bit Windows operating systems as well as 64-bit programs and includes a 64-bit DLL for executing 64-bit programs.

Hardware makers are moving forward on 64-bit drivers, and despite some bumpy going, the vendors expect to have the necessary infrastructure to support upcoming 64-bit OSes for enterprise customers.

The move to ditch 32-bit driver releases frees up AMD's driver team to focus its efforts solely on 64-bit versions going forward. We don't expect users will notice any difference though.

There's a difference between 64-bit and 32-bit operating systems, and it involves your PC, too.
