I have some solutions for most of you...
1. Goto AutoPatcher.com
and try there updater program for vista, it has every microsoft approved patch available for download and each month they release a new version with the latest patchs, they should fix a bunch of bugs with vista.
2. Boot vista DVD and select Repair instead of Install.
3. or Use recovery options to recover to a previous date.
One of the solutions should solve this for you.
This error code (80080005) is from programs trying to access a COM service incorrectly, there is not much you can do except remove that program to restore functionality.
