Because the constraint is to perform a full installation of Cubase, my plugins, etc., and run tests over time.
I don’t have enough PCs on hand to allow me to do that. I can’t see myself doing it if I had to conclude that it’s not a good idea. I work with it.
The other problem I expect to encounter is not being sure what to look for, in depth, to know if there is real compatibility or if I would risk encountering problems over time.
That’s why I’m asking.
But if I had an equivalent PC available, I would probably do it, yes.
In fact, it was after doing some research in this area that I ended up using the Atlas version of Windows for Cubase.
Ok, I thank you so much for your answer. It’s totally clear.
So, It’s not a good idea, I guess.
This is where the real potential for a “gotcha” lives. Testing isn’t just a good idea, it’s required because you may have component requirements that simply won’t run on Server, and you’ll probably want to know that up front. This is a perfect use-case for a VM though, and Broadcom is now giving away VMWare Workstation Pro for free (since last year).
Well, that’s not what he said 
You can absolutely optimize and run Server as a workstation specifically configured for performance of foreground applications and (nearly) mirror Win10/Win11 usability otherwise. You just have “do that.” And in my opinion, if your workflow supports it, it’s actually a very reasonable solution.
That said, and to save you some trouble, “no,” you can’t install Cubendo on Windows Server. While you can install and sign-in to SDA, the C13/C14 installers (verified) fail to install and cite failure to meet “minimum OS requirements.” You may be able to trick the installers via any potential number of methods, but right out of the box you can’t do it.
So while it still may be an interesting project to embark on, from a production perspective, I wouldn’t bother with it. Not only is it not supported in the first place, but the devs have explicitly prevented it, and that will likely manifest itself in issues with future updates and patches. My opinion is that it would otherwise run just fine, but I can see why they force requirements checks on install. I would absolutely expect similar issues with most plug-in vendors as well.
Just my buck-o-five.
Ok! my english is pretty average sometime, but I had understood that it’s an idea… little bit risky… So thx for precisions.
