UiPath cannot communicate with Explorer: error when passing to 2018.3.3 Enterprise

Hello,

I have updated the Studio Enterprise Edition from 2016.2.6379, to a major version, the 2018.3.3.

After opening one workflow, i get the following error:
18.3.3+Branch.master.Sha.dad278851683d948236b522f6a0c8dd584803e65

Source: Open Browser

Message: Cannot communicate with Internet Explorer browser.

Exception Type: UiPath.Core.BrowserOperationException

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

Can someone kindly help me?
It opens Explorer, but doesn’t insert the url.

Hi @CamiCat,

Can you verify that you have used the attach window or open the browser ?
