32 bit vs 64 bit FTDI driver
I use LABVIEW 32 bit and I cannot change it to 64 bit what can I do else?
FTDI FT4222 driver is tested only with 32-bit LabVIEW. Having said that, the most application can be built into a 32-bit version of LabVIEW with few exceptions where other dependencies of applications are 64-bit so it’s necessary to build in 64-bit. In such a case, please feel free to contact for further support.
We purchased 64-bit LabVIEW, but this driver only supports 32-bit LabVIEW. Should we purchase 32-bit LabVIEW again?
Not necessarily. Usually, the same LabVIEW license works for both 32-bit and 64-bit versions. Refer NI website here that indicates LabVIEW doesn’t license 32-bit and 64-bit separately. It comes together all the time. It would be just a matter of installing a 32-bit version and using the same license key.
JKI VIPM shows the FTDI driver as 64 bit, but you say it doesn’t support 64-bit?
There is some glitch here where JKI VIPM shows the FTDI FT4222 as 64-bit, but the driver in itself only supports in 32-bit.
To be more precise, JKI VIPM can compile all LabVIEW layers to 64-bit LabVIEW but does not compile the DLLs associated with the driver. There is a chance that if you replace the DLLs with 64-bit version, chances are they work, however, this replacement is not tested. Please feel free to contact for further support.
