How do I get PDFs from AXLR8 systems to download to Acrobat instead of showing in Chrome?

First Adjust your Chrome settings to choose your preference.

A. Go to Settings from the top RHS menu in Chrome. Settings is near the ottom of that menu.

B. Choose “Privacy and Security”

C. Choose PDFs

D. Set Downlaod as the action you require as default

Make Adobe Acrobat your default PDF application

It probably already is. However, if not, this is achieved by making Adobe your default app for PDF files (see this article on how to do it for Outlook and mail messages and apply the same principle).
