Place this to designated locations;

FGM148Javelin	>>	mods\update\x64\dlcpacks

hud_reticle.gfx >>	mods\update\update.rpf\x64\patch\data\cdimages\scaleform_generic.rpf\
or
mods\update\update.rpf\x64\data\cdimages\scaleform_generic.rpf\

It depends on your game version... I can't be sure which one exactly would be best for which version since I don't have all of them separately, you need to try this out yourself.


Then edit the dlclist.xml in mods\update\update.rpf\common\data;

		<Item>dlcpacks:/FGM148Javelin/</Item>
