Can we get a screen capture?
I don't think this is a problem with feral-heart, it is a problem with your computer settings.
Does your computer have different accounts? Typically on a computer shared by family, there is one account for each child(or one for all of them), and one for the parents, and one guest. Typically the parent's account is an administrator, and they ban downloading or installing on the children's account. Try asking your parents (or the account admin) to help you download it from their account.
