I am trying to use an NI USB-8451 controlled by some Labview written (and proven to work) by a colleague. When I tried to run his code, I got an error saying I needed to install a dll: ni845x.dll.
So, I found the NI downloader for the Windows 7 64-bit version of that dll (I'm running Windows 7, 64-bit). When I try to run the downloaded .exe (NI-845x_212.exe) I get this message:
"The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher." But different versions for x86 and x64 are not offered.
What next?
