MiKTeX is available on the CTAN[1] and on CD-R/DVD-R.
You can download MiKTeX from CTAN with the help of MiKTeX Net Installer (see the section called “Installing a complete MiKTeX system”).
If you cannot easily download more than 400 MB (the complete MiKTeX distribution), then you may wish to obtain a copy of the MiKTeX CD-R/DVD-R. Visit the CD-R/DVD-R info page, for more information.
The MiKTeX CD-R/DVD-R allows you to install MiKTeX on the hard-disk or to run the programs directly from the CD-R/DVD-R.
