Possible reasons and solution:
1.Delete dfb2xx.dll, and try to start software again.
2.The driver might not be installed. Just install it manually.
Open, click on “Downloads,” and choose from:
KT200II Offline Installation Package (The Official Deal)
ECUHELP KT200II Software (For Online Use)

3. Too many clicks: this might cause some conflicts with other programs running in the background. Unplug your device, plug it back in, and start the software again.
