Hi Mike,
It should be in the Eventide folder under Newfangled EQuivocate. If you're on Windows please double check that the plug-in is installed in the directory Live is using for VST plug-ins. You can check this in the settings, then un-install and re-install to make sure it's correct. Finally, you might consider installing only the 64 bit version on Windows (or 32 bit, if that's what you're using).
