Thank you for your answer Richard Letts and aLTeReGo just to be in the same page, FoE at the moment of first install replicates all the installed software, including the licenses, so i dont need two licenses of each module , one for the primary and one for the secondary... ¿i'm correct?
I went to the FoE admin guide, but it wasn't very clear the part of the licensing of the modules to be protected.
Looks Like i need to do a clean install... Thanks
