Windows 8 is now officially supported in the latest version of Worldox GX3. Note that the integration is only available in Windows 8 "Legacy Mode" - not in the "metro" or "modern" mode.
That said, Assemblage, Attach Plus, Virtuoso and Symphony Suite are not yet fully supported in Windows 8. Timeline on integration for these applications are still TBD - so please keep this in mind if you have plans to update.
If you are considering upgrading to Windows 8, please be sure to coordinate a GX3 upgrade with Trumpet. Our upgrade calendar is currently booked a few weeks out, so be sure to plan ahead! You can contact us at firstname.lastname@example.org to schedule your upgrade.
