Hi,
I have been using the "FPGA Interface C API" in combination with a NI-PXI-7852R board with success!
My question is, because I have an Windows7 x64 operating system, I would like to use this API as native x64 bit process.
Unfortunately the most important library ("niFpga.dll") only exists as on 32bit (x86) library. Also there is no distinction in the fpha.h header file for Win32 or Win64 builds.
In the "FPGA Interface C API Help file" the requirements state the following:
Supported development operating system Windows 7 Professional (32-bit or 64-bit version) Supported target operating system Windows (any supported development operating system)
How do I build 64-bit application with the C FPGA API?
Best Regards,
Marco

The same problem with us.
We have developed a NI C-RIO based measurement software under matlab with the ni fpga - mex interface, and have problems with 64 bit matlab on windows 7. Is there a 64 bit version of the nifpga.dll?

Hallo,
Unfortunately I have to say that the "nifpga.dll" file is only support x32 bit and doesn't support x64 bit yet.
I hope that as soon as possible we will see the new version of this file which will support x64 bit too.
Best regards,

Hello,
in our company we would like to integrate flexRIO hardware into our 64bit applications, so 64bit native support by Labview FPGA C API would be preferable.
Does anybody have any news about x64 version of "nifpga.dll"?

Hi,
After searching for you I can say that our R&D are working on that and hope they will release the x64 version as soon as possible but when, is not clear.

any more information on x64 windows 7 for FPGA? it could help with our operating systems here!

Hi,
Have a look at the supported operating systems for the 14.o verison of he FPGA INterface C API:

This link refers to the operating system installed on the computer. The FPGA Interface C API can run on 64-bit Windows but only as a 32-bit application. We want to build 64-bit applications.
Is there any updates on 64-bit application support? This is becoming a big problem for us because other vendors no longer support 32-bit applications.

To clarify, the link I was referring to was the link posted by JosD.

I talked with an NI Application Engineer and they informed me that there is is a 64-bit FPGA DLL. To fined the DLLs on a 64-bit Windows computer:
* The 64-bit NI FPGA DLL can be found here: C:\Windows\System32\NiFpga.dll
* The 32-bit NI FPGA DLL can be found here: C:\Windows\SysWOW64\NiFpga.dll
The 64-bit DLLs are kept in System32 while the 32-bit DLLs are kept in SysWOW64, as unintuitive as that may be.
