The Gaussian for Windows g03w is installed under E:\g03w. The g03w program (windows frame) can be opened by opening the program group and there click the item g03w. Now the g03w frame starts. Since there is a problem with the g03w surface (e.g. crashes when the archive is generated), it is better to work without the g03w surface. See the link Running Gaussian Jobs under Windows.

In order to follow memory and cpu usage press [Strg] + [Alt] + [Entf]. Now the windows task manager opens.
