Manufacturer code not shown in the list when creating a project?
You have to update your masterdata file. Normally when Manufacturer Tool starts and there is a newer version of the masterdata it asks you to update it. Once you update it, your manufacturer name will be shown. If you still don't get the notification, then you can download the file from here: https://update.knx.org/data/XML/project-20/knx_master.xml and copy it to the folders:
- C:\Program Files (x86)\KNX Manufacturer Tool 5.7\XML\project-20
