Help Installing .NET Framework 3.5 Languages when Framework 4.6.1 is previously installed

[OregonStateUGR]

I'm trying to install NI-DAQmx 8.8 for another software program. Because NI-DAQmx 8.8 requires .net framework 3.5, I've been trying to install .NET framework 3.5.  However, I wasn't able to do it.  Can anyone tell me how to resolve this issue?

Thanks in  advance!

Hi OregonStateUGR,

The .NET 3.5 Languages item that shows up in the installer for DAQmx isn't actually the .NET Framework from Microsoft, it's the support for .NET with DAQmx. So first, you will need to install .NET 3.5 from Microsoft, download found here. Once you have that installed, you should be able to proceed with the DAQmx installer like normal. Let me know if that does not fix things and we can go from there! 

Thanks,
