If you don't want to bother reading the full install documentation and just want to install everything in TeX Live, on a Unix-like system, a minimal recipe follows.
Non-interactive default installation on anything but Windows:
Changing defaults:
The Unix instructions work. If you prefer a native Mac installer, use MacTeX instead.
The rest of this page explains the above in more detail.
You do not need to remove an installation of a previous release, or any system-provided TeX; multiple releases of TL can coexist on the same system without conflict.
A separate page describes various ways to acquire the software. It boils down to either getting the DVD from a TeX user group (ideally by becoming a member), or downloading in various ways. Except on Windows, your system must provide a standard Perl installation with the usual core modules. (For Windows, TeX Live comes with its own Perl.)
For regular installations via download, we highly recommend installing the LWP Perl package if you don't have it.
If you're re-installing after a previous attempt, be sure to completely remove your failed installation. By default, this would be in these two directories (on Unix-like systems):
rm -rf /usr/local/texlive/2026 rm -rf ~/.texlive2026
You do not need to be root (administrator on Windows) to install, use, or manage TeX Live. Indeed, we recommend installing it as a normal user, except on macOS, where it's conventional to install as administrator. (Information about shared installations.) As always, you need to have permission to write into the destination directory, but TeX Live itself does not care if you are root or not.
Once you have the TeX Live distribution, run the install-tl script to install (on Windows, ), like this:
cd /your/unpacked/directory perl install-tl [... messages omitted ...] Enter command: i [... when done, see below for post-install ...]
To change the installation directories or other options, read the prompts and instructions. The default is to install into parallel directories named by the release year, so that any given release can be run independently, merely by adjusting the search path.
The installer supports text, graphical, and batch interfaces:
For information on all of the installer options, run , or see the install-tl documentation page.
It can take an hour or more to copy all the files. If you are downloading over the network, by default a nearby CTAN mirror is automatically chosen. If you have problems, we recommend choosing a specific mirror and then running instead of relying on the automatic redirection.
To install an older TeX Live, see the acquire.html#past section here.
After the installation finishes, you must add the directory of TeX
Live binaries to your PATH—except on Windows, where the installer
takes care of this. The installer shows the exact lines that should be
added. As an example, for Bourne-compatible shells (e.g., in
or ):
Use the initialization file and syntax for your shell, your
installation directory, and your binary platform name instead of
. After editing the init file, log out and log back in.
If you have multiple TeX installations on a given machine, you need to change the search path to switch between them—except on macOS, which uses another method.
The default is to configure the programs for the A4 paper size. To make the default be 8.5x11 letter-size paper, you can use the ‘o’ menu option before i(nstalling), or run after installation (and after setting your PATH).
After a successful installation, please try processing simple test documents, such as .
If you're looking for a front-end with which to edit files: on Windows, TeX Live installs TeXworks; and MacTeX installs TeXShop. A plethora of dedicated TeX editors are also available. In addition, any plain text editor will work.
If you want to update packages from CTAN after installation, see these examples of using tlmgr. This is not required, or even necessarily recommended; it's up to you to decide if it makes sense to get continuing updates in your particular situation.
Typically the main binaries are not updated in TeX Live between major releases. If you want to get updates for LuaTeX and other packages and programs that aren't officially released yet, they may be available in the TLContrib repository, or you may need to compile the sources yourself.
