I would like to know for the info on how to add a livery to the L100 manually as the ACE utility is not supporting the expansions.

jc - I have done this myself a few times.  

Make sure the textures in the new add-on match in configuration what is already in the sim.  If you have an add-on that has just the basic textures in it, do this:  
1-Copy an existing texture already in the aircraft folder back into the aircraft folder.  It will say "copy of xxxx.txt"
2-Rename this to the new texture you want to display.
3-Move the basic textures you want to add to the aircraft into the new (copied) folder.  Overwrite when prompted.
4-Use one of the existing config entries already in the "aircraft.cfg" file as a starting point.  Be sure the "model" entry matches what you know your new aircraft to be ("E", "H", or "J" 130).  Be sure the new texture is sequentially the next one in line in the config file.  You should change the "title" block in the cfg addition to match what your new texture name will be.  Change all appropriate entries in the original cfg write-up you copied.  This should be title, model, possibly cockpit, texture, call sign and flight number, and description.  It should work fine after that.
