10

I want to install a portable Tex Live in windows 10. But after searching online I just get this from the Tex Live guide.

The -portable installer option (or V command in the text installer or corresponding GUI option) creates a completely self-contained TEX Live installation under a common root and forgoes system integration. You can create such an installation directly on a USB stick, or copy it to a USB stick afterwards.

To run TEX using this portable installation, you need to add the appropriate binary directory to the search path during your terminal session, as usual.

On Windows, you can double-click tl-tray-menu at the root of the installation and create a temporary ‘tray menu’ offering a choice of a few common tasks, as shown in this screenshot.

The ‘More…’ entry explains how you can customize this menu.

Any more instructions in detail? What should I do?

  • Oh... You need to go Simple Install > Install and THEN you have a GUI appearing with a range of different options, including portable installation.

As of Mar 2022 the GUI option is no longer available.

Use the following method as described in The TeX Live Guide—2022 - 4.2 Portable (USB) installations.

"The -portable installer option (or V command in the text installer or corresponding GUI option) creates a completely self-contained TeX Live installation under a common root and forgoes system integration. You can create such an installation directly on a USB stick, or copy it to a USB stick afterwards."
