Is there a product that can convert an MS Access database file to an executable EXE file?

No, there is not. However, there is a free Microsoft Access runtime available which enables you to run an MS Access database on a system without having to install the full version. There is a runtime version for each version of MS Access. Below are links to the runtime downloads for MS Access 2007 through MS Access 2016:
