LibreOffice Base Portable Doesn't See Any ODBC Data Sources

Hi everyone, I’m trying to connect to an Access database via an ODBC connection. Everything is set up correctly, and when using the installed version of LibreOffice I can access and edit the database without any issues. However, I need to do the same thing on another computer where I don’t have admin access, so I decided to use LibreOffice Portable. Unfortunately, when I try to select the data source, nothing appears. Does anyone know what the problem is? Thanks!
