Instalation: .Place everything into your Fallout New Vegas Data Directory, don't forget to check the esp. .Or if you use a mod manger simply Download with manager and activate the mod there. .I recommend using a Mod Manager of any type makes things a lot easier and faster when installing any mod. If you have missing mesh or texture error try toggle Archive Invalidation:Invalidated, Off and On. It took me 3 days to create a fully funtioning Ammo, Projectile and Recipe lists for both Weapons i hope it's as every bit as good as the original Bethesda Rock-It Launcher from Fallout 3! Any questions just ask and if you find any problems related to this mod let me know.
