This color scheme mimics the Millenium color scheme from versions AIS 5 through AIS 10. The Millenium color scheme in Release 11 and above is a little darker background that the previous versions. To Install, select the registry version that matches your version of Inventor or Inventor Professional. Double click on the version to install the color Scheme in Inventor. It will be necessary to restart Inventor before the color schemes will appear in Application Options. To use, go to Tools > Application Options, and Select Colors. Select EasyStreet and Apply.
