Steinberg Download Assistant doesn't start

I’ve just bought the upgrade from Dorico 2 to Dorico 3, but Steinberg Download Assistant won’t start — so I can’t download the new Dorico version (?).

I installed the newest version of SDA and made sure my local Java version is up-to-date just in case. Here’s the error I get when I try to run SDA from the command line:

Help! What can I do to make this work?


Welcome to the forum, Adrian. I’m sorry you’re having problems getting Dorico installed. On Mac, SDA crashes are often (weirdly) caused by font problems: can you try running FontBook and eliminate any errors it complains about?

In the meantime, here are direct links to the Dorico Pro 3 installer, the Dorico Pro 3 Sounds installer, and the Dorico 3 Version History.

Thanks, Daniel! I asked Font Book to verify all my fonts, and it didn’t find any issues. Fortunately I was able to install Dorico 3 with that direct link. Much appreciated.


Hi Daniel - this may not be your department entirely but I am having the same issue with the Download Assistant not running (Mojave 10.14.6) - I am trying to install Cunbase 11, 4 Knob piano and Dorico 2. Any help much appreciated. Derek

I couldn’t get Download Assistant to authorize when trying to install a Cubase upgrade yesterday: Upon launch, it took me to sign in to the Steinberg website, and after I signed in nothing happened. The solution was to use Brave browser instead of Safari. (I tried that after reading a forum post saying that Tor browser resolved the issue.) If you’re having a similar issue, give this a try.

Many thanks for the tip. I can download the Assistant ok, but it won’t run despite enabling it in the Privacy settings… Best D.

Sorry to hear you’re having problems, @derek10. You can download Cubase 11 and Dorico 2 directly from the Steinberg web site, but I’m afraid I can’t immediately lay my hands on a link for 4Knob Piano. I suggest you try opening a ticket with the support team for their help with that.
