Hi -
I was having the same problem (and had verified multiple times that all the versions matched for install on roboRIO, and I had the 2016 FRC update to NI, and I had been in LabVIEW 2015 and was using the v19 image, etc.
It turns out that the fix is in a earlier posting ... where the previous year's built "wpilib" hadn't been deleted when I thought I had deleted everything in order to do a fresh install of the tools for 2016 (including a new version of Eclipse and Java). If you do this:
If that's the case, for some reason the plugins must be failing to update the files. Close Eclipse, delete your C:\Users\USERNAME\wpilib directory (where USERNAME is your username), then open Eclipse again.
that worked for me.
I am going to submit a document change request against the WPI documentation to include this on the troubleshooting page about "Image Check Failure", as following the steps there don't work.
It would be nice if the implementation of the plug-in worked correctly though.
Good luck!
