Open browser - cannot communicate with browser

Help

Hi

I’m trying to run my robot on a Windows 10 machine, it worked fine on Windows 7, but now when it tries to open a browser, I get:

18.3.1+Branch.master.Sha.4c05f670b311e90ee097c589605b399e9bee4874

Source: Launch & log-in to SM9

Message: Cannot communicate with the browser, please check the UiPath extension.

Exception Type: UiPath.Core.BrowserOperationException

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:

I have searched around this topic; suggested solutions were adding the site to trusted sites, allowing active scripting in the security settings, and running regsvr32.exe oleacc.dll as admin, all of which I have done to no avail…

  • Remove the old extension.
  • UiPath-> Start → Tools → Chrome Extension.
  • Goto Extensions → Enable Chrome Entension.

Thanks,

I went to UiPath->Start->Tools & clicked to download the Chrome Extension, then opened Chrome & clicked Enable Extension on the pop-up.

That appears to have sorted it, thankyou both :slight_smile:
