I am using Windows 10, UFT version is 12.54, and my Edge browser is 90.0.818.66 (64 bit). I followed the steps in the link below
https://eyeontesting.com/answers/microsoft-edge-browser-and-uft-1254/#gsc.tab=0
And I used, SystemUtil.Run "C:\Program Files (x86)\HP\Unified Functional Testing\bin\MicrosoftWebDriver.exe", "<my test url>"
to launch the browser and get the URL, but it does not work.
You can use this 2 commands, both should work:
SystemUtil.Run "msedge.exe"
WebUtil.LaunchBrowser "Edge"
