I THINK I FIGURED IT OUT!!! Forgive my enthusiasm, but I have been battling
this Vista Error 80070490 problem for almost two years now. Microsoft has
been no help at all, and HP did not give me the Vista Ultimate disk when I
bought the laptop so updating using the disk was not an option.
Today I manually downloaded Windows Installer 4.5 from the following webpage
and saved it to my desktop;
http://support.microsoft.com/kb/942288/en-us
Once that was downloaded, I installed it on my PC.
I then downloaded the System Update Readiness Tool for Windows Vista from
the following webpage and saved it to my desktop;
http://support.microsoft.com/kb/947821
Once that was downloaded I installed it on my PC.
These installations seemed to take a few hours. At times it looked like
things had froze up. I didn’t mess with anything and just let it do it’s
thing. A few hours later they were both installed. I don’t know which one of
these programs done the trick, but I really don’t care at this point. I
opened the Windows Updater, and searched for updates. Things immediately
started happening that I had not seen in almost two years. It first updated
the platform with service pack 1, then all the other updates I have not been
able to get.
Good luck.
