So the CD autoruns something? You just put the CD in and the error appears? If that's the case, browse the CD and see if you spot a file called autorun.inf Open up Notepad and drag that file into the blank Notepad window and you should see the contents of that file. Copy 'n paste it here so we can see what is trying to execute. If that is NOT the case, then do you double click on any particular file to view it? In which case, considering the error refers to HTML, try opening a browser window and dragging that file into it. If it's an HTML file, you should get something. Besides an error.
