Hi, what is the OS of your computer? Did you try it on Windows 7? Please install the driver from website to have a try: http://www.autel.com/autelcms/u/cms/www/201511/10055352nlsu.zip.

 If using on Windows 8 / 8.1

for installation of the drivers

 I had the same issue, I have Windows 7. I downloaded the suite and managed to install without unzipping the file. Once I figured that out, I unzipped and then had to tell it where the driver was. I had help with that step so I can't get better detailed steps, sorry.
