I have problems with the KT200 programmer "Selection driver not active", can you provide information on how to figure out this issue?


Possible solutions to the problem are:
1.Maybe tool is not recognized. To fix this issue, try resetting your PC ,unplug and plug the usb again and will be fine.

2.or driver issue, check device manager first, and then watch the video on how to update the driver:

3.It is also possible that your firewall is turned on and your antivirus is not uninstalled. If this is the case, uninstall the KT200 software, turn off all firewalls, uninstall the antivirus, and then reinstall the KT200 software.
