The Welcome Organization is auto created once the extension "ThingworxManufacturingApps-8.0.0-00-extension" is imported successfully.
I would recommend you to import the manufacturing apps extension again and check the installation results to see if you are getting some error .
If the import is successful , you will be asked to refresh the composer . Once you click yes , you can check the organizations again.
Log time no reply, sorry.
As you received the answer, [Wellcome] was not.
I abandoned this extension environment. I created the environment again and carried out Express Install. The result came to [Wellcome] without problems.
Thank you for your response. I would be pleased if you could get an answer next time.
