This is an Administrator Permissions problem, please follow the steps below:
On your desktop, double-click 'My computer' or open Windows Explorer, select your boot drive (C:), right-click on the drive and open 'Properties' on the display menu.
When the Properties window appears, on the tabs, select 'Security'.
On the 'Group or User Names' list, select 'Administrator' and click the 'Edit' button. You may need to do this within Control Panel for your specific operating system.
