Recently acquired a Graphtec FC7000MK-2 - 160. Trying to install the driver to my pc running Windows 7 Professional. I do not have a disk and downloaded everything from Graphtec support website. It copies the files but when it goes to install them it says to wait then after about a minute a box pops up and says "Installation has stopped". I do not have the usb cable attached to the computer. Any help is greatly appreciated.
