Windows/Linux/Mac Eclipse plugin to compile and upload arduino sketches

Hi,
I try to install Eclipse IDE for Arduino Due (ARM Cortex ATSAM3X8E uC) on Windows Vista Business, I installed Sketch 1.5.7.
I followed your instructions and installed Indigo Reliease 2.
I am stacked at step 3.6, I cannot unzipp any of the files for Windows 32 bit from this site, I tried 6 different files, and received error message
*.gz file is corrupt, CRC failure for each one.

I located Arduino plugin on 'Eclipse market' but the installation doe not work:
Error message
Cannot complete the install because one or more required items could not be found.
Software being installed: Arduino eclipse extensions 2.2.0.1 (it.baeyens.arduino.feature.feature.group 2.2.0.1)
Missing requirement: Arduino eclipse plugin 2.2.0.1 (it.baeyens.arduino.core 2.2.0.1) requires 'package org.eclipse.cdt.core.language.settings.providers 0.0.0' but it could not be found
Cannot satisfy dependency:
From: Arduino eclipse extensions 2.2.0.1 (it.baeyens.arduino.feature.feature.group 2.2.0.1)
To: it.baeyens.arduino.core [2.2.0.1]

Any idea? Thanks very much for your help.
