I see under the Home window and the Utilities tab is shows constituents and when that is selected is opens an explorer window then you can right click and click on "Select" and then is shows the constituents. It use to work with RMC only without going through all of those extra steps.
I think I have it fixed. It works now.
When I RMC and select properties the “Opens with” was "unknown", so I selected Alibre and now it works.
Some how must have become un-registered with the multi installs?
