Intego X8 software will replace your existing X6 versions. As such, all settings will be lost and replaced in the new version.
If you are interested in keeping a copy of your previous settings, you may do so by choosing File/ Export Settings (or Profile) in the top menu bar for any Intego software that supports this feature.
NOTE: X6 settings cannot be used with Intego X8 software. These files should only be used when reinstalling X6 software is necessary.
