CPN Tools is a Windows program. We support 32 and 64 bit versions of Windows 7 and Windows 8. Windows Vista and Windows XP are not supported, but CPN Tools often runs on those versions.
The CPN simulator also runs on Linux and Mac OS X. The Linux version is unsupported as we do not have any internal users running Linux only. The Mac OS X version is supported on the at any time newest version of OS X, currently 10.8.
The CPN Tools GUI can run under various virtualization software. We support Parallels Desktop and VMWare Workstation/Player. Other virtualization solutions may work but are unsupported. For more information about running CPN Tools in a virtual machine, refer to this knowledge base article.
