How to add Windows for 2nd user account on Mac

Hi, I have 2 user accounts on my mac, 1 for me and 1 for my daughter. I have installed parallels and windows 7 on my account and all works fine. If I switch to my daughters account and try to run windows it says "unable to connect hard disk 1" and then "unable to connect cd/dvd1".

What I would like to have is windows running on my account and then the ability to switch to my daughters account and also run windows on her account at the same time. Is this possible?

Thanks
