Prism 7 for Windows runs under either the 32- or 64-bit versions of Windows Vista, 7, 8 or 10.  Prism will run in a screen as small as 800 x 540. While it runs fine on 64 bit versions of Windows, it is a 32 bit program.

Prism 7 for Macintosh requires OS X 10.9 (Mavericks) or later. If you use OS X 10.7 or 10.8, Prism will launch and seems to run ok but we haven't tested Prism thoroughly on these versions of OS X and can't provide much support.

Prism windows requires 60 megabytes of space on the hard drive. Prism Mac requires 80 megabytes space.
