It's been a while so you may have figured it out already, but I had to find a way to push it since I maintain a lab space. Download the .zip, right click on the EndNote X7.4 Updater.app and select Show Package Contents. Navigate to Contents/Resources/ and grab the applePatch and Patchfile.patch items.
With those two components you can patch with the following command:
applyPatch -d "Applications/EndNote X7" -i Patchfile.patch. You will, of course, need to specify the location of applyPatch and Patchfile.patch in the previous command.
Once complete, you'll want to copy the latest Cite While You Write bundle: cp -R "/Applications/EndNote X7/Cite While You Write/EndNote CWYW Word 2011.bundle" "/Applications/Microsoft Office 2011/Office/Startup/Word/"
The downside of EndNote patching is that if you're more than one release behind you can't just patch the latest version and call it a day. You'll need to patch each version until you're running the latest. I have a deployment script that just removes the existing version from /Applications, copies the initial release, and runs through each patch file one at a time (not a long process). You could modify this process or use an entirely different one, but this has worked fine for me.
