education version of previous framemaker

[#1]

I'm an educator.  How do I purchase the previous version, I think it's the 2015 version, of Framemaker?

You probably have a Volume Licence – check with Adobe Support to see if you can add another serial number for a prior version downloaded via the Licensing site.
