Where can I download Native access 2 version before 3.19.0 Thanks
On one of the pages on the website it says "legacy installers" are not supported for Windows, possibly that includes older versions of NA 2. As far as I can tell, the older versions you're looking for don't appear to be on the website and are perhaps not available for that reason. Maybe if you contact Support, they can help. There's no way to contact support except through the website at https://support.native-instruments.com/
