If you choose to register to download the software, be aware that you will not receive the product CD. The downloadable product software is available in English only.

When you register to download the product software, Microsoft will send you an e-mail message with download instructions.

After you have completed the download registration process, you will receive an e-mail message with a link to the download page. On the download page, you will see a link to the Setup file and a Product Key for the software you wish to install. The file will be in ISO format and must be burned to a CD before you can install the software on your computer.

The download files are large (approximately 450 megabytes) so the download may take a considerable time to complete. Microsoft recommends only those with broadband, ADSL or other high-speed Internet connections attempt this download.
