<p>[The rest of this paragraph is only relevant after release.] The <code>bin/windows</code> directory of a CRAN site contains binaries for a base distribution and a large number of add-on packages from CRAN to run on 64-bit Windows.</p>
<p>R is best tested on current versions of Windows 10 and Windows Server 2022 with UTF-8 as the charset encoding. It works also on Windows 11. It runs on older versions of Windows, but normally with other charset encoding and may require manual installation of the Universal C Runtime (UCRT).</p>
<p>Your file system must allow long file names (as is likely except perhaps for some network-mounted systems). If it does not also support conversion to short name equivalents (a.k.a. DOS 8.3 names), then R <em>must</em> be installed in a path that does not contain spaces.</p>
<p>Installation is <em>via</em> the installer <code>R-4.3.1-win.exe</code>. Just double-click on the icon and follow the instructions. You can uninstall R from the Control Panel.</p>
<p>Installation is <em>via</em> the installer <code>R-4.3.2-win.exe</code>. Just double-click on the icon and follow the instructions. You can uninstall R from the Control Panel.</p>
<p>You will be asked to choose a language for installation: that choice applies to both installation and un-installation but not to running R itself.</p>
<p>See the <a href="https://CRAN.R-project.org/bin/windows/base/rw-FAQ.html">R Windows FAQ</a> for more details on the binary installer and for information on use on older Windows systems.</p>

<p>[The rest of this paragraph is only relevant after release.] The front page of a CRAN site has a link ‘Download R for (Mac) OS X’ which takes you to a new page. Two files are offered for download, <code>R-4.4.0 Under development-arm64.pkg</code> and <code>R-4.4.0 Under development.pkg</code>. Both are for macOS 11 or later (Big Sur, Monterey, Ventura, …).</p>
<p>The first runs is for ‘Apple Silicon’ (aka ‘M1’ or ‘M2’) Macs, the second for older Macs with an <code>x86_64</code> (Intel) CPU.</p>

It is a little faster (and for some tasks, considerably so) but may give different numerical results from the more common <code>x86_64</code> platforms (on Windows, Linux, … as well as macOS) as ARM hardware lacks extended-precision floating-point operations.</p><div class="no-row-height column-margin column-container"><li id="fn1"><p><sup>1</sup>&nbsp;You may be asked to install Rosetta at first use – <a href="https://support.apple.com/en-us/HT211861" class="uri">https://support.apple.com/en-us/HT211861</a> – which may need administrator privileges.</p></li></div></div>
<p>It is important that if you use a binary installer package that your OS is fully updated: look at ‘Software Update’ in ‘System Preferences’ to be sure.</p>
<p>To install, just double-click on the icon of the file you downloaded. At the ‘Installation Type’ stage, note the option to ‘Customize’. This currently shows four components: everyone will need the ‘R Framework’ component: the remaining components are optional. (The ‘Tcl/Tk’ component is needed to use package <strong>tcltk</strong>. The ‘Texinfo’ component is only needed by those installing source packages or R from its sources.)</p>
