Visual Basic Question

I have a software driver for an old scientific instrument that is described in a brief manual this way: "The acquisition driver is a tool that allows developers to write their own Windows based programs that can acquire data from any Michelson series spectrometer. The programs can be developed with any programming environment that supports calling standard Windows 16bit DLLs. Examples of such environments are Visual Basic and Visual C++ from Microsoft ( up to version 1.5 ), Delphi and C++ from Borland, Labview from National instruments. This document assumes that the reader is familiar with all the concepts surrounding DLLs and Windows programming. It is a reference guide that explains the parameters of the functions that make up the Bomem acquisition driver and how they are used to acquire data." I recently purchased Visual Basic 4.0 Standard Edition, but the first pages of the reference indicate that it is a 32 bit only version. Which version of Visual Basic will allow me to call this driver?
