Error 0x80004005 DLLRegisterServer

I'm not sure if this is the right formum to ask this on but here goes.
I've got an app that I update on client systems with a script. The
script unregisters dll's, then overwrites them, then registers the new
ones. On Vista, the app fails with "cannot create active X object"
which means the dll's are not registered properly.
So I went to the Run form and tried to manually register one of them.
I receive an error. So I went to a command prompt, told it to run as
Admin, and was succesfull in registering the dll.
How do you get into Admin mode in a script. I cannot go to every Vista
computer and manually register 12 dll's. I must be able to automate it.
Thanks for any advice.

I found the answer so I thought I would share it with you.
If I have my users turn off User Account Control (UAC), the script
driven updates will register properly.
It is located on one of the pages for managing user accounts.
It's probably a good idea to turn it off with any installation or
update, then turn it back on.
