How to Solve KESS V2 FW 4.026 "Protocol not compatible with version FW" Error?

Solution for KESS v2 FW protocol error (Win-7 and Win-XP)

To do this, you first have to uninstall the already installed software and the drivers. Afterwards we start with step:
1. Disable Internet connection

2. Install the K-Suite 2.06 Full Version including drivers (Microsoft Visual C ++ 2005 SP1 and USBDEVICEDRV 1.00.011).
The KESS device is not yet connected to your computer.

3. After successful installation, K-Suite will open automatically (no error message may occur during installation, otherwise you will have to repeat the installation). Select the desired language and exit the program.

4. Now you have to connect the KESS device via USB and wait for the automatic driver installation. (K-Suite not yet opens)

5. Right-click the K-Suite icon to open the file path. (Win-XP: right-click on the K-Suite icon, then open the properties, in the lower left you can open the file path) Marks the entire content in the folder and deletes it.

6. Opens the “Token Reset Folder” and copies the entire contents (it is the data from K-Suite 2.08). Now you change back to the already installed file path (here you just deleted all files) and insert the copied records. In addition, you copy the help folder (can be found on the supplied CD) and also paste it into the already installed file path. Now you can close all windows and start K-Suite.

The Kess V2 device will now be updated. This may take a little time. As soon as the main menu of K-Suite opens, version 2.08 should be visible. The message “Protocol not compatible with version FW” should no longer appear. If everything was successful, you can close K-Suite again and install the updates (2.10, 2.12, … etc) one at a time. The KESS v2 master clone device can remain connected to the computer. The important thing is that you only install the updates. Not the drivers (Microsoft Visual C ++ 2005 SP1 and USBDEVICEDRV 1.00.011).

How to Solve KESS v2 firmware 4.036 “External exception EEFFACE” error?
If the error message “External exception EEFFACE” appears, you must close the program. Now disconnects the Kess device, reinstalls the version at which this error occurred. This time with the USBDEVICEDRV 1.00.011, but without Microsoft Visual C ++ 2005 SP1. After installation reconnect the KESS device and start K-Suite.
