Important instruction for Internet Explorer® Users: While using this course, you will be asked to open a number of Microsoft Excel® workbooks. When an Excel file is opened from a web page hyperlink, Internet Explorer normally opens it in its own window, instead of invoking Microsoft Excel. This is true for other Microsoft Office documents too (Microsoft Word® and PowerPoint® documents). This needs to be changed by adjusting settings on your computer.
