Can only offer a couple ideas:
1) Have you tried system restore to a date before the problem started? (Start - Programs - Accessories - System Tools - System restore)
2) Error 1638 usually means exactly what it says - trying to reinstall or update a single program that's already been installed - not every program. Do you remember installing or updating anything new just before the problem started? If so, can you uninstall it?
3) Are you able to install anything in Safe Mode? To get into safe mode, tap F8 at the boot screen and select safe mode.
Beyond that, it would help to know whether its XP, Vista, or Win7.
