Error: The Designer x64 reported: The feature "FlowChartMode" is not licensed.
This is most likely caused by a licensing error or an issue that can arise from the AlteryxService shutting down unexpectedly. It can also be due to an incorrect or expired license, or a correct license not being installed with admin rights, or in the case of Runtime-only users (this type of license has been phased out for all but a few legacy clients).
You can check your license by going into Alteryx, clicking Options> Manage Licenses. Expired licenses are in red. Click on the active license to see the enabled features:
If you see this error, please verify that it is the correct, current license, and reinstall using appropriate admin permissions.
Still seeing the error? Please contact fulfillment@alteryx.com for license resolution.
Happy Alteryx-ing!
