That message indicates you do not have admin privileges, is this your personal PC or a company's?

You will have to log in to your admin level account to do it.

i am the only user on this computer and i am the administrator... (i checked it.)

Britton30 said:

Try this then. Built-in Administrator Account - Enable or Disable

Are you able to log into the hidden Admin account?

Try this for the drivers.

Yes,i was able to log into the hidden admin account but it didnt work...
and about the drivers: i tried to install every possible dirver,the newest or the oldest and it wont work both ways...

Please provide the specific video card (model number) that you are trying to update. Also, where are you getting the drivers from, and which ones are they? Link?

Thanks.
