No HUD on liveries?

[Jonathan Poller 1]

I've downloaded some liveries, installed them and works okay, besides there is no HUD/HUG.....how come?

Because the airlines don't use them! You can enable them in the FMC.

Some operators dont use the HUG system and dont have them installed. You can install it yourself with the CDU.

See the Introduction pdf starting page 49. Each livery comes with an ini file that represents the aircraft options that particular airline have selected. EDIT: Two other posts in the two minutes it took me to write a response
