How can I tell if I am Administrator?

Do the following to determine whether you have Administrative privileges:

For Windows 7, 10 and Vista:

On your desktop, click on Start (lower left-hand corner of your desktop)
Select Control Panel (Settings then Control Panel for Windows 10)
Double click on User Accounts.
A list of users will be displayed, along with the Group in which they belong.
The software should be installed from a user with Administrator status.
