SUMMARY
As a 32-bit application, Visual FoxPro requires a 32-bit operating environment. Therefore, the Win32s subsystem is installed when the Visual FoxPro setup is run in Windows or Windows for Workgroups. This article briefly describes the Win32s subsystem and provides Knowledge Base references that answer frequently asked questions.
MORE INFORMATION
Win32s provides a set of DLLs and a virtual device driver (VxD) that allow Win32-based applications to run on top of Windows or Windows for Workgroups.
The Visual FoxPro setup detects the current operating system and installs the Win32s subsystem if Windows (or Windows for Workgroups) is running. A WIN32S directory containing the Win32s Dynamic Link Libraries (DLL) is created in your SYSTEM or WINDOWS\SYSTEM directory. The WIN32S.EXE and WIN32S16.DLL are installed in your WINDOWS\SYSTEM directory, and the [386 enh] section of the SYSTEM.INI is modified to include Win32s drivers.
For general information about Win32s, please see the following articles in the Microsoft Knowledge Base:

If you are experiencing difficulties installing Win32s or cannot start Visual FoxPro in Windows or Windows for Workgroups, please see the following articles in the Microsoft Knowledge Base: 106715 Troubleshooting Win32s Installation Problems
122326 BUG: Win32s Setup May Fail if BUFFERS or FILES Set Too Small
117153 PRB: Display Problems with Win32s and the S3 Driver NOTE: Win32s requires a 10 MB or larger permanent Windows swap file.
If you need to reinstall the Win32s subsystem, remove it first. You can't simply delete the WIN32S directory because deleting it does not remove references to the subsystem. For a step-by-step procedure, please see the following article in the Microsoft Knowledge Base:
