FFEXTERN and CVSINGLE now only support Internet Explorer 6 and 7 for HTML and XML/XSLT conversions. If you only have an earlier version available, use one of the convert options NoIE, FireFox (if installed), or HTMLWord (if Word is installed) to select an alternate HTML converter.
The built-in converter selected by option NoIE typically converts HTML documents between twice and three times as fast as using Internet Explorer, but may not successfully convert complex HTML syntax.
If you are converting documents in an application where you control the HTML files, you may be able to use a 5.x release of Internet Explorer successfully.
