It looks like your user account is set up as a 'standard user'. If you own the PC and have the authority to install software, go to start/control panel. When control panel opens, select 'user accounts and family safety', then 'user accounts'. You should see your own account (created when you first set up your PC) and a list of options. Select 'change your account type' from the list and then select the radio button next to 'administrator'. Apply the changes and all should be OK with the installation. Hope that helps.
