4 Installation and use under Windows

This section only applies to systems running Windows 9x or NT. If you run Windows 3.1, you will have to install emTeX from the top level systems directory by hand.

It is also necessary to have your Windows set up so that it uses the Microsoft Joliet extensions for reading CD-ROMs; simply look at the CD-ROM in Explorer and see whether it shows long, mixed-case, file names. If it does not, you cannot use the ready-to-run system on the CD-ROM.

This Win32 TeX systems includes a dvi previewer, Windvi, which is similar in usage to the established Unix xdvi. The documentation can be found in texmf/doc/html/windvi/windvi.html.

4.1 Running from the CD-ROM

You can run all the TeX programs directly off the CD-ROM, and have access to all the macros and fonts immediately, at the price of a slower performance than if you install on the hard disk. To work effectively one needs to modify environment variables and to create some small auxiliary directories on a hard disk. These directories will contain necessary configuration files allowing the user to modify programs settings and to generate a necessary format file. Moreover, automatically generated font files will be stored there too. All these preliminary steps are performed by a program TeXSetup.exe to be called in a directory setupw32/ of the CD-ROM. Once the program is started and the auxiliary directory is choosen, select ‘Run CD’ option. When installation is complete, you will have to restart Windows. Now you can run the programs at a command prompt, or use a TeX editor which runs the programs from convenient menus.

4.2 Installing to your hard disk

Installation is started by letting the CD autostart, or by running the program TeXSetup.exe in the setupw32 directory, which works by accessing lists of collections and packages from the CD-ROM. It will allow you to select the level at which each collection is installed (see section 2.1) for a description of ‘collections’ and ‘packages’, and permits you to omit the documentation and/or source segments of the packages if your disk space is limited. You will be prompted for directories in which to install the main distribution, and your local configuration. In addition, you will be able to install a TeX editor and the PostScript viewer Ghostscript.

Please be aware that the choice of cluster size on DOS disk partitions can radically affect the size of your TeX installation. The support tree has hundreds of small files, and it is not unusual for a complete installation to take up to 4 times the amount of space used on the CD-ROM.

When installation is complete, you will have to restart Windows, and then you can run the TeX programs from a command prompt, or from the menu of any installed editor.

After a first installation not running off the CD-Rom, you will have the opportunity to add a single package to the installation. To do this, select ‘Add TeX Package’ option from ‘TeX Live! Maintenance’ system menu.

Running TeXSetup --help will display all available options.
