UFT 3.1 did export a file to "Wordperfect9" on my computer even though neither WP6 or WP7 installed. WP9 could not be automatically launched, but it was possible to print to file.
This file can be opened in Wordpad. It looks pretty good, but that's because the WP box drawing fonts were installed on this computer. Opening one of these files on another computer may or may not be totally successful. (Whether or not e-mailed.)
Reason? Ultimate Family Tree was hand tailored to work well several years ago with the then market leading WordPerfect programs.
UFT is now tailored to export properly to MSWord, and most of the (Report) RTF format files also work fine with Wordperfect9 and are backward compatible with the standalone UFT Editor. The problem is that you must convince UFT that you have MSWord or you can't export the latest and greatest at all.
