I have successfully installed the ODBC and OLEDB providers for Visual FoxPro 9 and they appear in the Windows 32-bit ODBC Data Sources under System DSN.
The drivers are discovered when I use Standalone Report Designer x86 from 17.2.23.1114 and older ones built against .NET Framework 4.0.
The same drivers are not found on the same machine when I use Standalone Report Designer x86 from 18.3.24.1218 built against .NET Framework 4.6.2.
