What is Win32?

Win32 refers to "32-bit Windows", in other words the recent versions of the Windows operating system which run in 32-bit mode. These include:

• Windows 95
• Windows NT 3.51
• Windows NT 4 and above

You cannot run the PennMUSH server on 16-bit Windows, which includes:

• Windows 3.1
• Windows for Workgroups 3.11

even if Win32s (the 32-bit Windows subsystem) is installed. This is because the server uses some 32-bit features, such as multiple threads, that are not supported under Win32s.
