Install Office.
Or install the "Microsoft Access Database Engine 2010 Redistributable"

Is there a certain way to configure "Microsoft Access Database Engine 2010 Redistributable" to be able to use "Microsoft.ACE.OLEDB.12.0"?

A proper connection string is:

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myExcel2007file.xlsm;
Extended Properties="Excel 12.0 Macro;HDR=YES";

See: Excel connection strings - ConnectionStrings.com[^]
