Two separate installers are now available for running PAPI on your Windows machine.
The full Windows Installer includes the complete test suite as both binaries and source code, along with electronic documentation.
The Matlab installer includes just the essential pieces of PAPI needed to run with Matlab.
PAPI for Windows requires a Pentium II or III, or an Athlon processor. It runs with Windows 2000 or XP. Pentium 4 support is in the works.
