    4 		Emacs version 25.3 for MS-Windows
    6   This README file describes how to set up and run a precompiled
    7   distribution of the latest version of GNU Emacs for MS-Windows.  You
    8   can find the precompiled distribution on the ftp.gnu.org server and
    9   its mirrors:
   11        ftp://ftp.gnu.org/gnu/emacs/windows/
   13   This server contains other distributions, including the full Emacs
   14   source distribution, as well as older releases of Emacs for Windows.
   16   Information on how to compile Emacs from sources on Windows is in
   17   the files README and INSTALL in the nt/ sub-directory of the
   18   top-level Emacs directory in the source distribution, as is this
   19   file under the name README.W32.  If you received this file as part
   20   of the Emacs source distribution, and are looking for information on
   21   how to build Emacs on MS-Windows, please read those 2 files and not
   22   this one.
   24 * Preliminaries
   26   There are two binary distributions named
   27   emacs-VER-x86_64-w64-mingw32.zip and emacs-VER-i686-w64-mingw32.zip,
   28   where VER is the Emacs version.  These are 64-bit and 32-bit builds,
   29   respectively.  If you are running a 32-bit version of MS-Windows,
   30   you need to install the 32-bit build; users of 64-bit Windows can
   31   use either build, but we recommend to install the 64-bit one, as it
   32   will be able to edit larger buffers and will generally run faster.
   34   The binary distribution has these top-level directories:
   36   + bin
   37   + libexec
   38   + share
   39   + var
   41 * Setting up Emacs
   43   To install Emacs, simply unpack the binary package into a directory
   44   of your choice.  If you use the Windows Explorer and its "Extract"
   45   action, by default this will be in a top-level directory with the
   46   same name as the zip file.
   48   We also provide a set of optional dependencies, in
   49   emacs-MVER-x86_64-deps.zip or emacs-MVER-i686-deps.zip respectively,
   50   where MVER is the major Emacs version that should use these
   51   libraries.  These provide Emacs with a number of additional optional
   52   capabilities, described in detail below.  To use these, unpack them
   53   directly over the emacs directory structure.  Note that, if
   54   extracting with the Windows Explorer, you will have to override the
   55   directory where it wants to put the file with the same directory
   56   where you extracted the Emacs binary package.
   58   Finally, and also optionally, you can run the program addpm.exe in
   59   the bin subdirectory which will place an icon for Emacs on the start
   60   page.  (This is no longer needed in latest versions of Emacs, so we
   61   recommend you not do that, as running addpm.exe will insert entries
   62   into the Registry which might get in the way if you upgrade to later
   63   versions without updating those entries, or would like to uninstall
   64   Emacs.)
   66   Emacs is completely portable.  You can create your own shortcut to
   67   runemacs.exe and place this wherever you find it convenient (the
   68   desktop and/or the Taskbar), or run it from a USB or network drive
   69   without copying or installing anything on the machine itself.
   71 * Prerequisites for Windows 9X
   73   The 32-bit build supports MS-Windows 9X (Windows 95/98/Me).  To run
   74   Emacs on these versions of Windows, you will need to have the
   75   Microsoft Layer for Unicode (MSLU) installed.  It can be downloaded
   76   from the Microsoft site, and comes in a form of a single dynamic
   77   library called UNICOWS.DLL.  If this library is not accessible to
   78   Emacs on Windows 9X, it will pop up a dialog saying that it cannot
   79   find the UNICOWS library, and will refuse to start up.
   81 * Starting Emacs
   83   To run Emacs, simply select Emacs from the Start Menu, or invoke
   84   runemacs.exe directly from Explorer or from a command prompt.  This
   85   will start Emacs in its default GUI mode, ready to use.  If you have
   86   never used Emacs before, you should follow the tutorial at this
   87   point (select Emacs Tutorial from the Help menu), since Emacs is
   88   quite different from ordinary Windows applications in many respects.
   90   If you want to use Emacs in tty or character mode within a command
   91   window, you can start it by typing "emacs -nw" at the command prompt.
   92   (Obviously, you need to ensure that the Emacs bin subdirectory is in
   93   your Path first, or specify the path to emacs.exe.)  The -nw
   94   (non-windowed) mode of operation is most useful if you have a telnet
   95   server on your machine, allowing you to run Emacs remotely.
   97 * EXE files included
   99   Emacs comes with the following executable files in the bin directory.
  101   + emacs.exe - The main Emacs executable.  As this is designed to run
  102     as both a text-mode application (emacs -nw) and as a GUI application,
  103     it will pop up a command prompt window if run directly from Explorer.
  105   + runemacs.exe - A wrapper for running Emacs as a GUI application
  106     without popping up a command prompt window.  If you create a
  107     desktop shortcut for invoking Emacs, make it point to this
  108     executable, not to emacs.exe.  If you pin Emacs to the task bar,
  109     edit the properties of the pinned shortcut (with Shift-right mouse
  110     click) to point to this executable.
  112   + emacsclient.exe - A command-line client program that can
  113     communicate with a running Emacs process.  See the `Emacs Server'
  114     node of the Emacs manual.
  116   + emacsclientw.exe - A version of emacsclient that does not open
  117     a command-line window.
  119   + addpm.exe - A basic installer that adds Emacs to "Start" menus and
  120     adds Emacs-related entries to the Windows Registry.
  122   + ctags.exe, etags.exe - Tools for generating tag files.  See the
  123     `Tags' node of the Emacs manual.
  125   + ebrowse.exe - A tool for generating C++ browse information.  See the
  126     `Ebrowse' manual.
  128   Several helper programs are in a version-specific subdirectory of
  129   the libexec directory:
  131   + cmdproxy.exe - Used internally by Emacs to work around problems with
  132     the native shells in various versions of Windows.
  134   + ddeclient.exe - A tool for interacting with DDE servers.  To be
  135     invoked as "ddeclient SERVER [TOPIC]", where SERVER is the DDE
  136     server name, and sends each line of its standard input to the DDE
  137     server using the DdeClientTransaction API.  This program is
  138     supposed to be invoked via the 'call-process-region' Emacs
  139     primitive.
  141   + hexl.exe - A tool for producing hex dumps of binary files.  See the
  142     `Editing Binary Files' node of the Emacs manual.
  144   + movemail.exe - A helper application for safely moving mail from
  145     a mail spool or POP server to a local user mailbox.  See the
  146     `Movemail' node of the Emacs manual.
  148   + profile.exe - A helper program that generates periodic events for
  149     profiling Emacs Lisp code.
  151   + update-game-score.exe - A utility for updating the score files of
  152     Emacs games.
  154 * Optional dependency libraries
  156   Emacs has built in support for XBM and PPM/PGM/PBM images, and the
  157   libXpm library is bundled, providing XPM support (required for color
  158   toolbar icons and splash screen).  Source for libXpm should be
  159   available from the same place from which you got this binary
  160   distribution.
  162   Emacs has a number of optional features which need additional
  163   libraries.  These are provided in a separate bundle of dependencies,
  164   as described above, and enable support for the following:
  166   - displaying inline images of many types (PNG, JPEG, GIF, TIFF, SVG)
  167   - SSL/TLS secure network communications (HTTPS, IMAPS, etc.)
  168   - HTML and XML parsing (necessary for the built-in EWW browser)
  169   - built-in decompression of compressed text
  171   The optional dependency libraries are in emacs-MVER-x86_64-deps.zip
  172   (64-bit) and emacs-MVER-i686-deps.zip (32-bit), and their sources
  173   are in emacs-MVER-deps-mingw-w64-src.zip, where MVER is the major
  174   version of Emacs that should use these dependencies.  Note that a
  175   64-bit Emacs will only work with the 64-bit dependencies, and the
  176   32-bit Emacs only with the 32-bit dependencies.
  178   Newer/updated builds for these optional libraries are available at
  179   http://msys2.github.io/ and
  180   http://sourceforge.net/projects/ezwinports/files/ (but you shouldn't
  181   need these except in emergencies).
  183   If you install the libraries in a directory different from where you
  184   have the Emacs executable programs, we recommend to add the
  185   directory with DLLs to your Path, so that Emacs will be able to find
  186   those DLLs when needed.
  188 * Installing Emacs with an existing MSYS2 installation
  190   You may also use Emacs with an existing MSYS2 installation by simply
  191   unpacking the Emacs distribution over MSYS2.  You can then use the
  192   'pacman' utility to install dependencies.  You should not use the
  193   optional dependencies bundle from this site, as this will overwrite
  194   MSYS2 files (the dependency bundle derives from MSYS2, but may be a
  195   different version).
  197   Some of the optional libraries need to be of certain versions to
  198   work with your Emacs binary.  Make sure you install those versions
  199   of dependencies, and no others.  Emacs variables such as
  200   libpng-version and libjpeg-version tell what versions of the
  201   corresponding libraries are expected by Emacs.  (We recommend that
  202   you use the dependency bundle, where these issues are always
  203   resolved.)
  205   To install the optional libraries, start the MSYS2 Bash window and
  206   type the following command:
  208     pacman -S PACKAGES
  210   where PACKAGES is the list of packages you want to install.  The
  211   full list is as follows:
  213     mingw-w64-x86_64-giflib
  214     mingw-w64-x86_64-gnutls
  215     mingw-w64-x86_64-libjpeg-turbo
  216     mingw-w64-x86_64-libpng
  217     mingw-w64-x86_64-librsvg
  218     mingw-w64-x86_64-libtiff
  219     mingw-w64-x86_64-libxml2
  220     mingw-w64-x86_64-xpm-nox
  222   You can type any subset of this list.  When asked whether to proceed
  223   with installation, answer Y.
  225   Alternatively, you could install the packages manually from this
  226   page:
  228    https://sourceforge.net/projects/msys2/files/REPOS/MINGW/x86_64/
  230   However, the packages there are not self-contained, so you will need
  231   to manually download all their dependencies as well.
  233 * Uninstalling Emacs
  235   If you should need to uninstall Emacs, simply delete all the files
  236   and subdirectories from the directory where it was unpacked (Emacs
  237   does not install or update any files in system directories or
  238   anywhere else).
  240   If you ran the addpm.exe program to create the Start menu icon, this
  241   can be removed by right-clicking and "Uninstall".
  243   Finally, addpm.exe also creates a few registry entries; these can be
  244   safely left, but if you really wish to remove them, all of the
  245   settings are written under the Software\GNU\Emacs key in
  246   HKEY_LOCAL_MACHINE, or if you didn't have administrator privileges
  247   when you installed, the same key in HKEY_CURRENT_USER.  Just delete
  248   the whole Software\GNU\Emacs key.
  250 * Troubleshooting
  252   Some known problems and their solutions can be found in the file
  253   etc\PROBLEMS in the unpacked Emacs distribution.
  255   Virus scanners
  257   Some virus scanners interfere with Emacs' use of subprocesses.  If you
  258   are unable to use subprocesses and you use Dr. Solomon's WinGuard or
  259   McAfee's Vshield, turn off "Scan all files" (WinGuard) or "boot sector
  260   scanning" (McAfee exclusion properties).
  262   Windows 9X
  264   On Windows 9X, make sure you have the UNICOWS.DLL library either in
  265   the same directory where you have emacs.exe or in the directory
  266   where system-wide DLLs are kept.
  268 * Further information
  270   The Emacs User manual describes Windows-specific issues in the
  271   appendix named "Emacs and Microsoft Windows/MS-DOS".  You can read
  272   it in Emacs by typing
  274         C-h r g Microsoft Windows RET
  276   This appendix is also available (as part of the entire manual) at
  278         http://www.gnu.org/software/emacs/manual/html_mono/emacs.html#Microsoft-Windows
  280   In addition to the manual, there is a mailing list for help with
  281   Emacs here:
  283        http://lists.gnu.org/mailman/listinfo/help-gnu-emacs
  285   To ask questions on this mailing list, send email to
  286   help-gnu-emacs@gnu.org.
  288   A mailing list for issues specifically related to the MS-Windows port
  289   of Emacs is here:
  291 	http://lists.gnu.org/mailman/listinfo/help-emacs-windows
  293   To ask questions on this mailing list, send email to
  294   help-emacs-windows@gnu.org.
  296 * Reporting bugs
  298   If you encounter a bug in this port of Emacs, we would like to hear
  299   about it.  First check the FAQ on the web page above to see if the bug
  300   is already known and if there are any workarounds.  Then check whether
  301   the bug has something to do with code in your `.emacs' file, e.g. by
  302   invoking Emacs with the "-Q" option.
  304   If you decide that it is a bug in Emacs, use the built in bug
  305   reporting facility to report it (from the menu: Help -> Send Bug Report).
  306   If you have not yet configured Emacs for mail, then when you press
  307   C-c C-c to send the report, it will ask you to paste the text of the
  308   report into your mail client.  If the bug is related to subprocesses,
  309   also specify which shell you are using (e.g., include the values of
  310   `shell-file-name' and `explicit-shell-file-name' in your message).
  312   Enjoy!
