How to Determine Which Version of Win32s Is Installed


The information in this article applies to:

  • Microsoft Win32s versions 1.1, 1.15, 1.2, 1.3, 1.3c


The "Win32s Programmer's Reference" describes how to use the GetWin32sInfo() function in a program to determine which version of Win32s is installed. This article explains how to determine which version of Win32s is installed interactively.


Use one of the following two methods to determine interactively which version of Win32s is installed:

  1. Check the WIN32S.INI file in your Windows system directory. The Version entry contains the major version and the build number ( This entry should be modified by any Win32-based application which installs a later version of Win32s on your Windows machine.

NOTE: Because it is up to the application vendor to set this value when installing Win32s, the value may not be accurate. Microsoft strongly urges all independent software vendors (ISVs) to modify the WIN32S.INI file so that this information is available to customers.

  1. If Win32s is installed on top of Windows for Workgroups, select the WIN32S16.DLL file from the Windows system directory in File Manager. Then from the File menu, choose Properties. The Version line contains the major version and the build number.
