Yes: install AmberTools17 in an directory tree headed by "amber16", and
point
your AMBERHOME environment variable there. When you need to run pmemd,
explicitly use .../amber14/bin/pmemd as the executable name.

There is nothing to buy: AmberTools17 has no license fee. And there is no
simple way to avoid using AmberTools17 to get the OHE residue to work
correctly.

[Finally, just an aside: people who purchase Amber16 now are eligible for
a free upgrade when Amber18 is released.]
