BleepingComputer.com: System Admin Permission

I keep getting a message in Spanish (I'm trying to download a Spanish language course) that says I can't download because I need the system admin to allow it. I'm the administrator as it''s only me on the home system but can't get to the area where I might allow it. The Windows help topic (an oxymoron) suggests creating a standard acct but if you're the only user you can't, go figure. I've tried the trusted site thing, saving the page as web folder (sorry, maybe stupid but I'm desperate) to circumvent the admin issue. Oh, I get that exclamation point in the message if that means anything.
I just want to learn a little Spanish, is that too much to ask....!?!
Muchas Gracias for any help
