Error Installing WPI Library for C++

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 (
Missing requirement: edu.wpi.first.wpilib.plugins.core (edu.wpi.first.wpilib.plugins.core requires ‘bundle org.eclipse.ant.launching 1.0.200’ but it could not be found
Cannot satisfy dependency:
From: WPILib Robot Development Core (
To: edu.wpi.first.wpilib.plugins.core []

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.

We had the same problem with the offline package, using the online install worked though.

‘bundle org.eclipse.ant.launching 1.0.200’

Perhaps you should try also manually installing this plugin on the target machine?
