Win32s 1.30

Win32s (Win32 subset) was an API layer for Windows 3.1 and Windows for Workgroups that allowed some Win32 applications that compiled with the subset of Windows NT API functions supported through 32->16 bit thunks. Certain functions such as threading and OpenGL were not supported. As Windows 3.1 was cooperatively multi-tasked, so are Win32s applications on 3.1 and memory space is still shared.

Win32s 1.30c is the final version.

For additional Win32s support files, resources, and a list of known compatible Win32 applications, see http://stephan.win31.de/w32slist.htm

Installation instructions

Note: Win32s 1.30, 1.30a, and 1.30c are known to crash on some emulators/virtualizers. If you encounter that problem, try 1.25a instead.
