Installing Architexa From Behind a Firewall

If you are unable to use the update site to install Architexa, you can install manually:

1. Download the zip file located at http://update.architexa.com/client/client.zip 
   (For manually installing the extended features use: http://update.architexa.com/client-extended/client-extended.zip)
2. Extract the zip file locally to a folder called "client"
3. In Eclipse:
   1. For Eclipse 3.5+, Help > Install New Software > Add > Local
   2. For earlier Eclipse versions, Software Updates > Find and Install > Search for new features to install > Help > New Local Site
   3. Browse to the client-extended folder just created and select it. Enter "Architexa" for Name.
