How does the Computer ID Change?

[innoshane]

Yesterday I was using an activated copy of NI Vision AI 2010.  Today when I went to open vision builder on that same machine computer, it stated I did not have a full licsense.  When I was in the license manager, it said that this product was already licensed on another computer.  When I pulled up the computer description, it gave me a different computer ID then what was on my activation email.  What can change the Computer ID and how do I get it back to the other computer ID that it is supposed to be?

Hi innoshane,

It depends on the specific computer for how it determines its ID. It could either be based off of you MAC address or your Hard Drive's serial number. Is this computer a desktop or laptop computer? Have you made any hardware changes to the computer since it has worked correctly?

Let me know about those questions and we can see if it is possible to force the computer to reference one of these options to get it back to the working ID.

After further searching, I found that the computer ID was based off the MAC Address of the computer's network card.  We have 3 Network cards in that computer, and after further questions,someone had restarted the computer with that card disabled and therefor the computer was no longer recongnized when it re-started.  I enabled the right card and disabled the others and it started to work correctly.  Thank you for your time and your response.
