Unable to use archive as offline plugin installation

[andrew_stubbs]

My development environment is set up in such a way that it is (unavoidably) unable to connect to the internet, new software must be transferred manually.

I attempted to install the activiti-designer plugin via the latest archive at http://www.activiti.org/designer/archived/ (activiti-designer-5.14.1.zip), as accessing the update site directly is not possible for me.

However I am unable to install the plugin, receiving the following error message when trying to install from the archive in Eclipse Kepler:

<blockcode>
Cannot complete the software install because one or more required items could not be found.
Software being installed: Activiti Eclipse BPMN 2.0 Designer 5.14.1 (org.activiti.designer.feature.feature.group 5.14.1)
Missing requirement: Activiti Designer - GUI 5.14.1 (org.activiti.designer.gui 5.14.1) requires 'bundle org.eclipse.emf 0.0.0' but it could not be found
Cannot satisfy dependency:
  From: Activiti Eclipse BPMN 2.0 Designer 5.14.1 (org.activiti.designer.feature.feature.group 5.14.1)
  To: org.activiti.designer.gui [5.14.1]
</blockcode>

My understanding was that by using the archived file directly I would be able to install the activiti-designer plugin offline, was this incorrect?
Should this work, but I've missed another dependency I need to install manually first? I tried searching for the requirement but seemed to be linked back to the original update site or some git repositories.

I have tried to install activiti designer plug-in 5.14.1 by using link http://www.activiti.org/designer/update. The issue I am facing is whenever tried from Mule Studio from Help–>Install New Software–>Putting that link and followed the wizard next, then gives me the error always as:

Cannot complete the install because one or more required items could not be found.
  Software being installed: Activiti Eclipse BPMN 2.0 Designer 5.14.1 (org.activiti.designer.feature.feature.group 5.14.1)
  Missing requirement: Activiti Eclipse BPMN 2.0 Designer 5.14.1 (org.activiti.designer.feature.feature.group 5.14.1) requires 'org.eclipse.emf.transaction 1.4.0' but it could not be found
So I am unable to complete plug-in installation. Please guide me on this aspect.

I managed to install Activiti Designer in eclipse Luna (standard edition) after manually adding the following dependencies:

http://www.eclipse.org/modeling/emf/downloads/?project=validation (version 1.8.0)
http://www.eclipse.org/modeling/emf/downloads/?project=transaction (version 1.8.0)

There is still an warning on an unknown dependency EMF Workspace (1.4.0) but it seems to be non-blocking and I don't see any issues using the designer.
