Make sure you have all other applications (and that means ALL) stopped, and have any anti-virus software temporarily disabled. If in doubt, reboot, turn off anti-virus, and then try again.
An error [-5006 : 0x8070020] has occurred while running the setup.
Please make sure you have finished any previous setup and closed other applications.
If the error still occurs, please contact your vendor: SAS Institute Inc..

Can either mean that a previous setup.exe really is still running or that you did not start this installation as a Windows Administrator.
