I received Foxwell NT510 at Jun 28 from http://www.foxwelltool.com/to work on a 2002 GM C1500. It did not come with the GM software installed, since I specified GM for my included 1 free vehicle make. I was asked to register on Foxwelltech.com website and download the program, my Serial number is NV516040XXXXX.
After successfully registered, I find nothing more. When I select the GM software and attempt to install, the website prompts me to click "here" to install a client, which fails to work. I've included a screen sh ot and the result of clicking on the "here" prompt.
I have attempted with both windows 7 and windows 10

Then, their engineer help set my serial number combine with GM program and then I just need update the device by following update procedure:

Finally, I figured it out...GM software is loaded. The OBD2 scanner works well. All other features work
Therefore, I think Foxwell NT510 is worth to have one although there are also a little bug, as long as the customer service response fast and help fix it up.

Does your GM software have the capability for key programming?
