@Gerald Wolfe:
Even after you install the actual program, it does not start automatically. Look in your Start Menu. The icon and name should be in there. After you click it, the program will open. If you are not signed into your Google account for the default browser, you will be asked to do so (including starting the default browser if it is not started). After you have successfully signed in, you can close the browser. Then you can do everything in the GDocsDrive program.
