Inventor installation CD

Hello,
I am not sure how unique our situation is as compared to other schools, but all internet is blocked for all the school computers except for a few areas. Even those computers who have access to the internet is monitered and most sites are blocked. My question is, Are we able to get a cd installation cd from First or AutoDesk through a re-seller? I have sent several emails to autodesk but have not recieved any responses. Thanks all
