Operating System Compatibility:

PHDWin is compatible with both 32 and 64 bit versions of: Windows 7, Windows 8, Windows 8.1, and Windows 10. As PHDWin is a 32-bit program, it will install in the “Program Files (x86)” directory on Windows 7 64-bit machines.

You may use PHDWin on a Mac using Apple’s Bootcamp solution. A Bootcamp solution requires full versions of Microsoft Windows and Microsoft Office Professional for Windows (32 bit) for full PHDWin operation. We do NOT recommend using VMWare or Parallels virtual machine software on Mac machines
