2.  When running the installation program you must specify which
    AutoCAD version you are updating (locked or unlocked). The update
    for the locked version should be applied to the network version
    of AutoCAD.

3.  The following installation instructions assume that you have
    installed AutoCAD for Windows or Windows NT in the \r13\win
    directory and AutoCAD for DOS in the \r13\dos directory on
    drive C. If you have installed AutoCAD on a drive other than C or
    in directories with names other than the defaults, substitute
    your drive/directory names in the commands listed below for the
    default directory names. These instructions also assume that your
    that you have copied and self-extracted these patches to c:\update.


AutoCAD for Windows or Windows NT
---------------------------------
Important: The R13c3_c2 installation program should not be run from a
DOS shell under Windows.

3a. Navigate to the directory that contains the Windows ACAD.EXE file.
    For example, enter the following at a DOS prompt:

      c:
      cd \r13\win

3b. To install the patch from a directory on the hard drive such
    as c:\update and your "common" directory is in the \r13\com
    directory on drive C, enter the following to install the unlocked
    version:

      c:\update\wininst c:\update c:\r13\com /U

    or the following to install the locked version:

      c:\update\wininst c:\update c:\r13\com /L

    and follow the instructions on the screen.

    If you plan to use the WHIP display driver you should install
    WinG. Refer to the WinG Installation instructions contained in the
    file READC3.TXT or READWHIP.TXT (this file is located in the 
    WHIP\WinG file C3WHIP.EXE).

    It is recommended that you upgrade to Win32s v.1.25 (however, it
    is not required). You can get the new version from your dealer or
    from the Microsoft forum on CompuServe.

4.  The patch is applied.

5.  Launch AutoCAD as you normally would.

AutoCAD for DOS
---------------
3a. Navigate to the directory that contains the DOS ACAD.EXE file.
    For example, enter the following at a DOS prompt:
     
      c:
      cd \r13\dos


3b. To install the patch from a directory on the hard drive such
    as c:\update and your "common" directory is in the \r13\com
    directory on drive C, enter the following to install the unlocked
    version:

      c:\update\wininst c:\update c:\r13\com /U

    or the following to install the locked version:

      c:\update\wininst c:\update c:\r13\com /L

    and follow the instructions on the screen.

4.  The patch is applied. The file, READC3.TXT, is also installed into 
    the AutoCAD R13 \DOS directory by the patch program if DOS is patched.  
    IMPORTANT NOTE: If DOS is not installed and patched, this file is
    not created. 

5.  Launch AutoCAD as you normally would.
