The CVI drivers for the HP3325 and HP3457 are very old it appears and were propabley created before plug and play and the need for DLL distribution. The only way to create the DLL required is with LabWindows and even then might take some effort to work. However, LabVIEW drivers do exist for the HP3325 and HP3457. Go
here, select Agilent as the manufacturer and download them. I don't know about your BP14xx. Who is the manufacturer and what is the exact model number.
