7710 - How to solve an "invalid host" error despite having a seemingly correct license file with the correct MAC address?
Lattice tools employ FlexNet Publisher (FNP) license management technology. When FNP licenses are generated, they are locked to a specific machine by using the FNP host ID.
The FNP host ID of a machine is typically the MAC address of the primary network interface on that machine.
The best way to recover a machine's HostID is to use the 'lmhostid' tool from the FlexNet utilities package:
In Windows Command Prompt, change directory to the path where "lmutil.exe" is saved. It is typically in C:\lscc\radiant\2024.2\ispfpga\bin\nt64
C:\lscc\radiant\2024.2\ispfpga\bin\nt64>lmutil lmhostid
C:\FlexNet\install_dir>lmutil lmhostid

The FlexNet host ID of this machine is ""81c645fec657 9ecbe866f889 0d43b0c0da55""
Only use ONE from the list of host IDs and request license with this host ID.
