How do I install Yahoo! Messenger with Voice?

For All Applications, All Operating Systems, and All Domains

Piece of cake. To install SBC Yahoo! Messenger with Voice Beta:

Close all running Applications except for your Internet browser.

Visit the SBC Yahoo! Messenger with Voice download page.

Click the "Get Started" button

Note: Download time can take anywhere from 1 to 15 minutes. You need 8MBs of free space to install SBC Yahoo! Messenger.

After installing, launch SBC Yahoo! Messenger with Voice Beta. If you have a Yahoo! ID and password already (that you use for SBC Yahoo! Mail, SBC Yahoo! Photos, Yahoo! Games, etc.), you can enter it. Otherwise, click the "Get Yahoo! ID" button to create a free Yahoo! Account.
