19c 32-bit client on a 32-bit Windows 10 computer?

Is the 19c 32-bit client installer a 32-bit architecture? We need to install a client on a Windows 32-bit computer for development with a VB6 32-bit application, but can't get the client installed. We are getting the error that the setup.exe isn't supported on the system. It looks like the installer is 64-bit, but we can find no documentation to support that guess.
