What 'same thing'?

then i tried to install diskeeper lite and when installing i get this  error 1920.service diskeeper failed to start verify that you have sufficient privileges  to start system services,im using computer admin account?

Are you using an account with admin privileges or not?

i tried to check te drive(disc)for errors and when i reboot and it starts checking it says cant open volume for direct access?

Really? After you boot you can't access the drive at boot time to check the disk? Hmm...
