Cannot communicate with Internet Explorer browser error

i use the open browser activity, but it post an error.
the phenomenon is that the Webpage opened long time and the IE would be open twice then post an error.
and i have used the solution Enhanced Protected Mode in Internet Explorer
and also used the solution Internet Explorer x64
but they all not worked.

Hai @fightblue… Have u install the extension of the browser?
If you are working in a server environment , U cant disable enhanced protected mode,
that will be a no go for IE for sure,maybe your network is preventing you from using any browser extensions, please make sure this is not the case as well.
