Error Installing WPI Library for C++

[Nathan Powell]

Greetings, all.

I am trying to install the WPI C++ library on a couple of offline computers for my team to use. I successfully installed Eclipse and tested it using the standard libraries and Cygwin. However, when I try to install the WPI C++ development tools using the offline method described on Screensteps, it gives me this error:

Cannot complete the install because one or more required items could not be found.
Software being installed: Robot C++ Development 0.1.0.201601072029 (edu.wpi.first.wpilib.plugins.cpp.feature.feature. group 0.1.0.201601072029)

Would it be a problem with the way I installed Eclipse, perhaps? Or the offline package I am using?

Thank you in advance for any assistance provided.
