Schneider Electric uses different physical mediums for authorization. Understanding this is key because the “authorization code” behaves differently depending on the medium.
| Type | Medium | How Code is Used | |------|--------|------------------| | Software License (Node-Locked) | Hard drive / registry | Code activates via Schneider’s Activation Wizard (online or offline). Tied to that PC’s hardware fingerprint. | | Hardware Dongle (USB Key) | USB dongle (usually green or gray) | The dongle contains the license. An authorization code is used to “write” the license onto the dongle (via License Update Center). | | Floating Network License | License server | Authorization code installed on a server. Clients borrow licenses. | | Subscription (EcoStruxure) | Cloud/Schneider account | No classic auth code. Activated via login and subscription ID. | unity pro xl authorization code
Most common confusion: Users mistake the installation serial number (printed on the CD/DVD or download page) for the authorization code. They are different. The serial number allows installation; the authorization code unlocks functionality.
