To me it sounds like you HTML is not locating your javascript libraries so you may not have the correct path set in your HTML.
So,
created a folder in your root c: called "fusioncharts". The complete path witll be "c:\fusioncharts" copy the contents of the unzipped download "js" folder to c:\fusioncharts. So in c:\fusioncharts you will see two folders, maps and themes, and 6 javascript files copy the attached HTML to the c:\fusioncharts folder in the c:\fusioncharts folder, doubleclick the file "firstchart.html" to load it into IE. You may get an "activex" or script warning since you are executing it locally. Go ahead and allow"blocked content" to run. the chart should now appear
Take a look at the HTML and you can see how the javascript libraries are referenced "relative" to the html file location.
Hope this helps.
