Error Code 80070490

[K. Emily]

I have searched repeatedly for a way to solve this problem so that Windows
will update automatically, however, I have yet to find anything that works.
I have a computer that is less than a year old that is a 32bit system,
running on Windows VISTA Home Premium. I have tried uninstalling and
reinstalling Windows Update, I have restored my system and I have attempted
to upgrade VISTA by using the VISTA DVD. When I install the DVD the only
option is to install a new "clean" version because there is a message saying
that the "Upgrade has been disabled."
I am wondering if anyone knows how to enable the Upgrade option so I can use
the DVD, or if anyone knows of a different way to solve this problem.
