In the previous week, I noticed that during the installation of SSE and RELM, in most case, after the setup, some unexpected errors occurs.
All steps are done well, but at the end something went wrong. Either the screen “loading” appears and nothing happens, or during the setup, at a point something must come but nothing happens.
In most case, for solving, I asked 2 questions:
Which Browser are you using?
and have you enable the “Popup” windows?
In general, some answers are Firefox, Chrome, IE for the 1st one and for the second one is simply “No”, why?
My recommendation is to use the firefox ESR branch and ensure that the “popup” window is not blocked.
