I had to recently reinstall NAV 2003 Pro Edition but when i get to the live update during the install it wont complete. I've re/uninstalled this program before a few times and never had the problem. Below is the following Error message i get.
LU1806: Live Update was not able to install any of the 1 updates that you selected. For More Information please click the "+"sign next to the updates that did not install. All Available updates were selected
