No. Challenge-response means the software running locally on your computer generates a challenge code, which the remote server (run by the developer) is given, and then returns a response code which the software is waiting to read and verify before proceeding.BONES wrote: Sat Oct 25, 2025 1:27 am You did because you called it "challenge-response", which implies an internet connection is ALWAYS required.
"Alway-on connection required" or "always-on internet" is what is used to refer to systems which require computers being always online.
The manual and website says that 3 activations is the limit. I haven't tried to go over it, so I will assume you are correct that the limit isn't enforced by the activation server. That's good to hear.BONES wrote: Sat Oct 25, 2025 1:27 am You may only be allowed three instances by the licensing agreement but that is not a physical limitation of the software. The fact you can do off-line activation ensures that. And As I've said, I've installed DUEN on at least a dozen computers over the years and never had any problem with activation limits. It just keeps installing and activating.
No. I need an internet connection only once to download the installer. I save it on a hard drive, which I also back up. I don't need an internet connection to download it, after that. However, because of the enforced challenge-response activation requirement, Synapse Audio's activation server needs to still be operational, and I do need some sort of internet connection -- either on the music computer, or another computer or device -- to activate a new installation.BONES wrote: Sat Oct 25, 2025 1:27 am You need internet access to download the installer anyway, so what's the problem? We live in a highly connected world.
If that requirement didn't exist, I could know that the software I paid for will still be installable in 20 years, assuming I keep a computer which is compatible with it. I have a Macintosh G4 here next to me, by the way, from 24 years ago, which can still run my old software and projects from the late 90s and early 2000s. I'm great at parties.
Maybe it sounds like a theoretical, made-up problem, but I've already been burned by shut-down activation servers for multiple products. Lessons hard-learned.
I'm not saying I won't ever use products like this. One of the DAWs I use is Bitwig, which has an online activation requirement. But, in the back of my head, I hesitate each time I add something new to my toolkit which has an online activation requirement. Each new one I add is a thing that will have some sort of guaranteed failure point in the future.
If Synapse Audio sold Proxima and Dune 3 at double the cost but without the activation requirement, I would pay for that without hesitation.
No, it tells you how to access Synapse Audio's licensing servers from a computer that's online but which isn't your music computer. If Synapse Audio's licensing servers go offline, you can't activate new installations of Synapse Audio products.BONES wrote: Sat Oct 25, 2025 1:27 am You are very definitely getting it wrong, as you have proven by pasting the activation procedure in here. It tells you exactly how to license your product off-line if you can't access the servers.
