Important change in the distribution: Emacs is now a 64-bit build!

Emacs Modified for Windows is a 64-bit (x64) distribution of GNU Emacs 25.3 (released September 11, 2017) bundled with a few select packages for R developers and LaTeX users.

The additions to stock Emacs are the following:

The distribution is based on the release version of emacs-w64, a native 64-bit distribution of GNU Emacs for Windows compiled with optimization and providing support for PNG, JPEG, TIFF, GIF and SVG images, XML2 and GnuTLS.

System requirements

This distribution requires a 64-Bit version of Microsoft Windows.

If you are still running a 32-bit version of Windows you need to install the 32-bit build. The last such version of the distribution was 25.2-modified-2.

Images and preview-latex mode

This version of Emacs bundles the libraries needed to display images in formats XPM, PNG, JPEG, TIFF, GIF and SVG supported on Windows since Emacs version 22.1. Among other things, this means that the toolbar displays in color, that the ESS toolbar displays correctly and that the preview-latex mode of AUCTeX works to its full extent. However, the latter requires to separately install Ghostscript and to make sure that the file gswin32c.exe or gswin64c.exe is in a folder along the PATH environment variable.

The previous comment also applies to the image conversion tool ImageMagick that may be required by Org. If you need the tool, install it and make sure its location is along the PATH.

Unix applications

Emacs sometimes uses external applications that are standard on Unix but not available on Windows (for example: diff, gzip). When needed, install the applications from the ezwinports project. To make sure Emacs can find the applications, include the folder where they are installed to the PATH environment variable. (With thanks to Laurent Pantera for the hint.)
