Open Browser "Cannot communicate with Internet Explorer Browser" open twice

Suddenly yesterday uipath during an Open Browser activity started to open IE twice.

The flow check if the browser is open, if not:

Open Browser (with a variable for the address based on values gathered before) ;
check if exists the IE Windows Security login window, if yes:
Attach Window
and set text for User and Password.

It was working perfectly since yesterday. Now when it reach this point it opens IE twice and break returning the “Cannot communicate with IE browser” message.

Any suggestions or anyone facing this?

Thanks in advance.

Hi @Bern

Can you check did group polise changed?

I had same problem on couple machines and I solved that with “start process” activity.
For the path you just need to pass path to your IE 32bit and in argument you just need to pass your url and that’s it! :slight_smile:

Hope this help!
