Hey, I am a longtime user of Audirvana, bought it for windows and mac plus the iOS app. But never in my life I will pay subscription for studio.
So is there still a way to install 3.5 again?
I tried this version: Audirvana 3.5 Download
but I got this error.
Any Ideas? Thank you 
If you write to support and they can find your original order they will probably provide you a link.
However, the latest version, Origin, is fantastic, and a one time purchase cost. Studio is also brilliant for streaming and radio. I only use my own library so Origin is for me.
I have a download of 3.5
Now the non subscription version called Audirvana Origin is available. You get a discount on upgrade from 3.5.
Hello @gabelrocker,
Does your computer is fully up to date? The issue you have is not related to Audirvāna but Windows itself.
