In the initial set-up you are given the option to run from CD, or to install full program to the hard drive. If you go into control panel/add/remove programs, highlight Autoroute and click on "Change", you may be able to alter from there. If not, then the best option is to un-install and on re-installing, look for the on-screen message asking if you want to install full program to your drive.That's the option I chose. Regards. j.
