When Microsoft released Office 2019 they made the default installation a 64-bit installation.  The default installation of all previous versions of Office was a 32-bit installation.

This has created a issue for anyone running an access database developed with a  32-bit version of access.

There is little or no benefit in converting/ running a 64 bit version of office unless you are running complex excel spreadsheets that exceed 1,048,576 rows by 16,384 columns

Follow these steps to change from a 64-bit to a 32-bit version of Microsoft Office

Step 1

Important: If you already installed the 64-bit version, but want to install the 32-bit version instead (or vice versa), you must uninstall the version you don't want before installing the version you do want. See “Office (64-bit or 32-bit) couldn’t be installed” error.
