For Chapter 8
	To access the InterAct tutorials over the Web, you will need to download the InterAct plug-in--but you will only need to do this once. To make this process easier, you can print this page now and follow these directions: Click on the Download InterAct button. A dialog box will ask you where you would like to save the file. Select a folder on your hard drive to save it in and make a note of the location to which you save it. Using your Windows Explorer (this can be found from the "Start" menu under "Programs"), locate the saved file and double-click on it to launch the installation. Make the appropriate selections in the dialog boxes as you proceed through the installation. Once the installation is completed, return to this Web site and select the InterAct problems that you would like to try. The InterAct plug-in will then be launched automatically.
