Error message “Wrong Protocol Version” appears when one of Leapwork component (Studio, Controller and Agent) are not running on same version.
Leapwork comes with three major components Studio, Controller and Agent(s), in order ensure consistency across the platform all of them should be running on same version.
To solve this issue download the latest version of Leapwork from here and install it on all the computers where you have either Studio, Controller and Agent(s) running, this will ensure same Leapwork version and latest features are available to you.
