Machine-Specific: The selicense.dat file is typically locked to a specific hardware ID, such as a MAC address (Ethernet ID) or a physical USB Dongle.
Placement: For a standalone (node-locked) installation, this file is generally placed in the \Program Files\Solid Edge V20\Program folder.
Version Compatibility: Licenses for modern versions (like Solid Edge 2020/2021) are not backward compatible with V20. You must have a specific V20 license file to run that version. Why You Might Need This "Piece" If you are trying to restore an old V20 installation:
