INTRODUCTION
------------

The enclosed WW0548 disk contains a revised Windows WIN87EM.DLL file.
You must be using Windows version 3.1 to use this dynamic-link library
(DLL) file. If you have a version of Windows earlier than 3.1, you do
not need to replace your current WIN87EM.DLL file. You also do not
need to replace your WIN87EM.DLL file unless you are using the Intel
80387 math coprocessor. The Intel 80486DX and 80486DX2 processors do
not require the new file.

Installation
------------

1. Exit Windows. The WIN87EM.DLL file that you will be replacing is
used by Windows and, therefore, cannot be updated while you are
running Windows.

2. Insert the enclosed WW0548 disk in your floppy disk drive.

3. Copy the file from the WW0548 disk to your Windows \SYSTEM
subdirectory. To do this, type the following from the command
prompt and press ENTER

copy :\win87em.dll

where is the letter of the floppy disk drive and
is the path to the Windows \SYSTEM subdirectory. For
example, if your Windows \SYSTEM subdirectory is \WINDOWS\SYSTEM on
drive C and you have inserted the WW0548 disk in drive A type the
following:

copy a:\win87em.dll c:\windows\system

4. Restart Windows.

The new WIN87EM.DLL file has now been installed and will be used by
Windows upon restarting.
