Install what program?
If you mean Windows Mail, it comes preinstalled with Vista.
You will need to set up a mail account in Windows Mail in order
to use it.
I see you posted with a Yahoo email address. Is that your
only email address? US-based free Yahoo accounts have webmail access
only, no POP access. Windows Mail handles POP mail but not Yahoo webmail.
Yahoo's solution is to pay for premium "Mail Plus" service:

and use the special settings for that service:

If you are OK with using a non-Yahoo email address, you have these other
solutions that will work with Windows Mail:
* Use the email address assigned to you by your ISP.
* Use a free Gmail, AOL, or Hotmail/Live account.
If you need more help with any of these solutions, just ask.
