Question: KT200 ECU Programmer was running ok last month. We tried to install the software on windows 7, 10 and 11 – disabled driver signature enforcement, we reinstalled the drivers several time, and used the reset button several times. Always after we open the application the buttons are grayed out and we can not use it. Any solution for this issue please?

Go to BIOS setting disable your secure boot 1st,and redisable driver signature enforce.

Open PC Settings, search for “Restore,” select “Reset this PC”
Then select Troubleshooting
Then select “Advanced Options”
Then select “Startup Settings”
Select “Restart” Finally,
Select “Disable Automatic Driver Signing”
