SL_E_SRV_INVALID_BINDING
SL_E_SRV_INVALID_BINDING (0xc004b006) is a Windows Software Licensing activation-service code. This code means the activation server could not validate the binding between the license and the device or installed Windows state. It can follow a significant hardware change, an edition mismatch, or an entitlement that does not apply to the current installation.
What to check
- Verify the installed edition and whether the device has a digital license linked to the intended Microsoft account.
- Check activation status before attempting another key change.
- If the device belongs to an organization, verify the permitted activation channel with the administrator.
