There are several causes for this message, you should read all the information before trying any one of these solutions.
1) This is a known issue in some versions of Crystal Reports, and there is a hot fix at http://support.businessobjects.com/library/kbase/articles/c2012318.asp.
Note that although the article’s metadata indicate this hotfix is for CR .NET, the body copy speaks only of CR 9.0. As such, apply this hotfix with some trepidation. On Win XP systems, you may want to make a retore point in case the hotfix messes up your installation.
2) On a Win 98 machine, exporting to HTML 3.2 or 4.0. There is no known fix at this time. http://support.businessobjects.com/library/kbase/articles/c2013300.asp
