Upgrade Warning 495: ODBC Core Not Installed by Default

InstallShield 2019

The ODBC core is not installed by default. If this is required by your setup project, select the MDAC merge module from the Redistributables view.

MDAC Prerequisite for ODBC Installation

Although InstallShield Professional provided an object that installed the ODBC core as well as ODBC drivers, InstallShield 2019 does not directly support this functionality. Because Microsoft requires you to install ODBC as a subset of MDAC, the Windows Installer does not support direct installation of the ODBC core.
