Hey there,

There is a great article about using the NI I/O Trace Functions that can be found below.

I wanted to inform you that more recent drivers do not install the I/O trace API and so it must be downloaded separately.

The latest IO Trace appears to be for LabVIEW 2014, not 2015.

I suspect you are not missing anything, but, in fact, have too much.  I tried doing a similar installation on one of my machines that has LabVIEW 2014 and 2016 installed.  I downloaded I/O Trace 2014 and tried to install it -- it said that nothing would be installed (and they were right, nothing was installed).

It is often the case with NI Software that "Version matters".  What I suspect is required is to have LabVIEW 2014, and no more recent version of LabVIEW, installed in order for I/O Trace 2014 to install properly.  In my own experience with installing and uninstalling LabVIEW, uninstalling is a much trickier operation than installing.  I have yet to be successful in doing an uninstallation of "the latest version" of LabVIEW -- there always seem to be pieces left over that make it so almost no LabVIEW version works successfully.  The only way I've been able to do a "partial rollback" is to do the following:

1. Go into Control Panel, Programs and Features, National Instrument Software, and "Remove All".
2. Reboot.
3. Reinstall the oldest version of LabVIEW that I want.  If there are any "Version-specific Toolkits" (like I/O Trace), install them after installing the other LabVIEW Program, Modules, and Toolkits for that Version.
4. Reboot.
5. Optionally, install the Device Drivers you need for this Version (you can also leave this to the final step).  Reboot.
6. Repeat Steps 3-5 with newer LabVIEW Distributions, always doing LabVIEW, Toolkits and Modules, Reboot, optional Device Drivers, Reboot.
7. If you have not yet installed Device Drivers (waiting until the end), do it now, and do the final Reboot.

This method has (almost always) worked for me.  A LabVIEW "uninstall" can take about as much time as a LabVIEW "install", so be patient.  Some of my experience with multiple versions of LabVIEW were made in the LabVIEW 2010-2014 era, and I did, on several occasions, try "selective removal of only the latest stuff".  This took a long time to uninstall, a long time to reinstall, and still didn't work, so I used the "Undo-it-All" technique described above and learned my lesson.

It is possible that if you only have LabVIEW 2014 and 2015, a selective "uninstall" will work, but I'll wager a dime that it will fail, and you'll just waste the time to "do the experiment" and have it fail.
