The information in the Troubleshooting Win32s installation document is sufficient to prepare a failed Win32s install for an attempt to reinstall it. The following is a list of all steps necessary to completely remove it from your system should you wish to do so. This is also the best way to ensure that an attempt to reinstall it will succeed.
To remove Win32s:
1.Remove the following line from the [386Enh] section in your SYSTEM.INI file:
where <WINDOWS> and <SYSTEM> are where the Windows and System directories are, respectively.
Most often this will be c:\windows and c:\windows\system.
2.Modify the following line from the [BOOT] section in the SYSTEM.INI file:
by changing it to the following (remove the reference to winmm16.dll):
3.Delete the following files from the <WINDOWS>\<SYSTEM> subdirectory or from the SYSTEM directory in network installations:
W32SYS.DLL
WIN32S16.DLL
WIN32S.INI
WINHLP32.EXE
WINDOWS.HLP
WINHLP32.HLP
WINHLP32.CNT
Important: It may not be possible to delete W32SYS.DLL while Windows is running. This occurs if you ran some Win32 application. It is recommended that you remove Win32s while in MS-DOS, not from an MS-DOS box.
4.Delete all the files in the <WINDOWS>\<SYSTEM>\WIN32S subdirectory or the <SYSTEM>\WIN32S subdirectory in network installations. Then delete subdirectory itself.
5.Restart Windows.
NOTE: <WINDOWS> refers to the
windows installation directory. On a networked Windows
installation, the system directory may be located on a remote
share. If you are only removing Win32s from your machine, then you
do not need to remove the shared files (in <SYSTEM> and
<SYSTEM>\WIN32S). Before removing these files from the
network share, make sure that all users that use Win32s have
removed the references to Win32s from the SYSTEM.INI file.
