Play at work (Need for Speed: Underground)

In General I sit at work,and the odd bloody boring. Decided pogamat in NFS,but the trouble is,on all my computers blocking the installation of applications and games including. Without admin rights will not install. And work another 8 hours...
There was one idea I want to turn to dear friends.
Good people,if you already installed the game,then Repack the folder with the established game archive and put it on some file sharing. I would be grateful. Thank you for your attention.
