Steinberg download assistant

I am trying to install the trial version of Dorico using the Steinberg Download Assistant but every time I open it, it says that it needs to download the latest version and does not progress anymore beyond that. Why is this so? This happens every time. Please help.
Thank you very much.

Similar problem but the Download Assistant just doesn’t launch (shows only “Launching the …” message with circle dots moving) or crashes at start.

Try right clicking and running it as administrator.
