I have been playing HCE for years. Recently tried installing the new .dll file (first time changing those files). When I run HCE I am told I need to update/upgrade my GE. Any guidance?

You'll have to be more specific regarding versions and filenames. But for general guidance:

 

 

 

Start with your 2015.027 patched HUCE from Matrix. Then apply any newer builds attached to this message.

 

Those newer builds are currently HC2017.013 (for the Game Engine (GE) and Scenario Editor (SE)) and HC2017.011 (for the DB Utilities and Battleset Builder, etc).

Where can I find HC2017.013?

Operative words being "any newer builds", as I write this, 2017.014 is the newest, replacing 2017.013.

Ok, where would I find 2017.14?

Here, but beware read first the Tony's warning on "beta testing guidelines", or do not install beyond 2017.011...
