Hi Evan,

Historically 64-bit LabVIEW is preferred only when there is an absolute benefit like high memory usage or real dependency on 64-bit drivers etc.  However, I can give a few suggestions like

  • Have you used FTDI 64-bit drivers yourselves?
  • A few things can go easily wrong in Call Library Function nodes like the pointer and its conversions, please ensure they are covered properly.
  • If you have other dependencies in 32-bit support, I would say the quickest trick could, open your project/files in 32-bit LabVIEW and build them.  Since you don’t need a separate license for 32-bit or 64-bit LabVIEW.  However, if your project really needs 64-bit dependencies or 64-bit benefits then the obvious rough route is to build 64-bit dependencies.  FYI: The driver I have here is for the FT4222 device and doesn’t support MPSSE on FT2xx.

Thanks
Ajay
