What does this mean?
 

Your account on the computer has to be an admin.

Great. My dad's account is super slow... and I never use my account. Okay whatever... thanks.

Go on your dad's account and make yourself an admin.

I suggest you edit out your email address or you's might get some spam for serious.

Oo.

Just make it where your computer accepts you as an admin and then you should be able to get it to work. Nice background by the way
