There is a anti virus software running (Office scan) but i cant turn it off as im here at work and its locked
This single sentence makes me guess, you're trying to install & run LW in a very customized network environment, which you can't control fully. This is not suitable for current LW beta at all, I guess. LW needs to be installed & run on a single workstation PC with real local Windows installation, on this PC's Administrator account at best or on an account belonging to this PC's Administrators group at least, with full administrative privileges. Also, it shouldn't be any AV or security software running and LW expects to be run with nearly exclusive access to the system resources, like memory, CPUs, storage and graphic subsystems.
