Which version of WP do you have? If you have WP6 or WP7, you should be able to automatically launch your reports. Refer to UFT Program "Help".
If you have WP8, the problem is with WordPerfect.
If you have WP9 (WP Office 2000), you must select UFT Editor "Print to File". Deselect "Automatic Launch". WP9 cannot be automatically launched from UFT because it was released after UFT3.0 was released.
Note: The Rich Text Format reports exported to the UFT Editor are for the most part the same as the ones automatically launched to MSWord. They will work with WP9. Your mileage may vary. If you are not satisfied with a report, select a different export until you get the best one available.
Why? "It aint necessarily the UFT programmers fault!"
Yes, this does not seem to make any sense, but if you are a Wordperfect fan thinking of upgrading to WP9, make a copy of this message before it disappears.
