Leapwork is committed to providing the best experience with latest browser versions and their drivers, following the same track Leapwork continuously updates itself to latest version of browsers and their drivers. After May, 2017 we updated the driver for Microsoft Edge browser from "Microsoft Web Driver 14" to "Microsoft Web Driver 15".
So, if you see any of the below messages then you need to update your Microsoft Web Driver.
If you are using Microsoft Edge 14 and have upgraded Leapwork to its latest release then you need to download the corresponding web driver 14 from here, and then copy and replace the downloaded "MicrosoftWebDriver.exe" in the Studio folder "C:\Program Files\LEAPTEST\Studio".
