The current version, 10.01, is available for different combinations of OS and platform. At this time there are four types of WWB, those being WWB.NET for the .NET object model (used with Visual Studio.NET 2005 and 2008 and Vista), .WWB-COM for the COM object model (Visual Studio and Visual Studio.NET earlier versions), both of which are used with all Windows 32 and 64-bit operating systems from Windows 95 to Windows Vista; the other two packages are for Windows CE and PocketPC & Windows Mobile. Earlier versions of WWB ran under Windows 3.1 and ostensibly OS/2 Warp 3 as well.
