Steinberg Download Assistant, it is the portal to download everything Steinberg and install to your computer.
You have the same issue I had.
Listen to this awesomeness,
Windows 7 has no more support by Microsoft.
Cubase 10 needed the latest update pack for Windows 7 to run.
As Microsoft dropped all support, they deleted all updates for Windows 7.
As such, Cubase 10 wouldn’t run.
So I decided to upgrade to windows 10.
Then it turned out that by Motherboard was incompatible with Windows 10.
Isn’t that awesome???
I had to trash my computer and fork out over £2,500 for a new PC…
So, unless you stay with Cubase 8 or 9 , you will have problems my friend.
But as I said, the download assistant won’t work with Windows 7, it’s all done so that people will keep buying stuff, isn’t that awesome???
I did put up a fight on a post about this (VST 2 plugins). You have no idea how much this angers me.
In short, no , they don’t have to trash anything. Leaving the old service packs wouldn’t kill Microsoft for people who cannot afford to buy new computers.
I love it how all industries work in tandem to get things unworkable to the point where people have to trash equipment they bought with their hard earned money…
