Thank you for the details.
with the older version 6.9.4 if I not check anything in internet id (see image) everytime the agent start it change the id.
This was an unexpected behavior, a bug (which masqueraded as a feature). We fixed it in the subsequent updates.
The correct behavior is this: when you do not
select "Generate a new Internet-ID code" , the ID will stay the same on the remote computer where you previously ran the Agent. However, if you do enable this checkbox, the ID will get generated anew. This is how it works in the current version.
As for getting a new ID generated each time you run the same Agent on the same computer
(i.e. a new ID for each session) , this feature is in our wish list just as Polina mentioned above.
Hope that helps.
