Following the video check in from last Tuesday (https://inputmapper.com/90-check-in-apr-18-2017-windows-10-exclusive-mode-fix-may-be-coming-for-im-1-7-and-1-6) I have since found the stand alone service does in fact fix the exclusive mode issues for both IM 1.7 and is backwards compatible with IM 1.6 and possibly earlier (untested).
The catch is that you MUST be on Windows 10 and the controller MUST be used via USB or using the Sony Wireless Adapter, purchased here: http://amzn.to/2oS15xG.
