Question

Creo Host ID Keeps changing (error (-9) invalid host ID)

Hi All,

In one of our machines, we installed Creo 12 with a Node locked license. Generated the license based on the host ID shown in the Creo installer. Creo runs perfectly. After a few days, it stops with the error (-9) invalid host ID. When we check, the previous host ID is no longer shown. It shows a whole different Host ID.

 

Any assistance would help. If not, we may have to escalate to PTC.

Regards.

Hi,

please run ipconfig /all > ip.txt in Command prompt window and upload ip.txt file.

 

My guess:

Problematic computer only contains WiFi network card -AND- MAC address randomization of this card is turned on.

The solution ... turn off MAC address randomization and get new license file.
