My code needs Microsoft Access Database Engine 2010 Redistributable" package for working correctly.
However the code is packaged in an MSI hence, we need to package the Access Database Engine 2010 (exe) also with in an MSI. But the question is, is it possible to get merge modules (msm) for Access Data Base engine as well?
The merge module for access database engine is supposed to exist. try http://www.installsite.org/pages/en/msi/msm.htm which has the below info.
Alternatively, you can write your own msm which microsoft tells you how to do: https://learn.microsoft.com/en-us/windows/desktop/msi/authoring-merge-modules
