Unfortunately Autodesk does not allow that the plugins run in Revit LT.

I have installed the trial version into Revit LT & the printer Bullzip PDF is available & great quality.  The tab does not appear embedded in the the program however & neither can I find a reference to Docuflow on my computer anhywhere.  Is this because it is a trial, version?  Is it because it does not embed in Revit LT?  How can I trial the export features without it being available in the trial?  Wanting to roll this out across 15 workstations but not until I can see all the benefits applying to Revit LT.
