You DO NOT replace HostID manually in license file. All codes in license file are generated by PTC generator using provided MAC address, so simple editing license file won't work.


After running ipconfig /all you should check, if HostID in license file matches any of physical addresses for network cards.If it doesn't, Windows doesn't see your network card and therefore Creo is unable to start, since license doesn't match. In that case you should investigate why the network card isn't available or generate new license file using physical address of one of existing network cards.

If there is a network card with MAC address matching HostID in license file, you may need to change the priority of network cards in Windows registry, to make Creo see the network card again.

As per error, license is generated for MAC address which is not active on machine. Did you change the machine?

I have used creo on this device only. It is Windows 10.

Check available host id's on machine.

 

Type command ipconfig /all in DOS window and check the physical address for Ethernet card. That address should match with HOST ID in license file.
