Are you sure it's VISTA SP 3, not Office SP3, or the .NET framework SP3? Because you're absolutely right, there is no SP3 for Vista yet. Well, at least not publicly available. If you right-click Computer in your start menu, and click Properties at the bottom, it should tell you which service pack you're on.
And to fix the SP2 install issue, perhaps try downloading it directly from the Microsoft Update website and installing it manually?

After googling for so long, at last I find a way to update to vista sp2....
To do so, you need to change the HEX values of the CSDVersion to the following registry keys from 300 to 100:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Windows
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Control\Windows
100 = SP1, 200 = SP2, 300 = SP3
After that just restart the computer and no problem to update to vista sp2... :emotion-1:
