Opcom firmware 1.70 review from a customer:
Great tool and speedy delivery!
Needed to program a new key and it worked like a charm!
Other options like read & reset fault codes worked great as well.
Some small probs installing the driver in Win 8.1 but that was easily solved:
Make sure you’re not signed in (Sign out if you already are)
Click restart and hold the “Shift” key
Choose “Troubleshoot” -> “Advanced options” -> “Startup Settings” and click “Restart”
After restart choose “7) Disable driver signature enforcement”
Install the drivers and reboot, that’s what did the job for me!
Thanks and good luck to all you new buyers!
