How do I transfer the SoMachineV4.3 software license to another PC?

To transfer the license with SoMachine V4,1, V4,2, and V4.3 you just need to install the software on the new PC and register the software using the Schneider Electric License Manager again with the same account / email address to get a new permanent license.

For help with licensing, please contact the licensing support center near you:

For the OPC UA and ETEST licenses can be and should be returned to install them on the new PC with the same licenses key if needed.
