Object Library issue with my VBA code

[freuzo]

Hi,
I've office 2013 and 2019 installed. With the 2013 version 15.0 it's just Excel and Access for my developpment.
With 2019 I have outlook, word, powerpoint, publisher and skype (and NOT ACCESS 2019 OR EXCEL 2019).

So I made some excel's code on my office 2013 but they can't run in another pc with just 2013 intalled. They got Object Library 16.0 Missing error.
And the code isn't about others apps automation. For that I usually use CreateObject to avoid referencing issues.

Is the 2019 installation somehow added object library 16.0 to my 2013 office ?
Aren't they in separated folders ?
Is there a way to have 2013 with is native 15.0 Library AND 2019 installed in the same pc ??

Thanks...
