First clear up your Temp File/Cache, Reboot and try again. Best and easier to use CCleaner.
If it doesnt help, try this : Rt Click Computer > Manage > Services > Stop the "Cryptographic Service" and rename the "Catroot2" folder situated in C:\Windows\System32\Catroot to something like say Catroot2X. Reboot. Now run the update/hotfix installers again. This action will re-generate a new Catroot2 folder and the updates/hotfixes, should hopefully install OK.
If still you have a problem then, go to C:\Windows\Windows Update.log and look for the most recent entry. Any failed updates will have error code/s written next to them. Note them down.
Now refer the Windows Update Error Codes This will give you the direction in which you may have to look for the solution. Or check out this Microsoft resource. There is some nice info here too at UpdateXP some of which may find relevance to Vista.
