It's possible to run v3 without actually "installing" it - after you've done the v3 install at home, copy the entire folder (like c:\Program Files (x86)\MoI 3.0 beta Mar-17-2013) including all sub-folders onto a USB key drive, then at work just copy that same folder onto your desktop or documents directory and you should then be able to run the MoI.exe that's in that folder.

That should work for running MoI v3 on your work machine even if your IT department has disabled admin rights and so you can't run regular installers, unless they have some other more unusual kinds of system locks in place.
