cannot find the livery folder to manually install liveries and livery manager wont install zip file downloads

Hello, 

i am trying to install KLM liveries for the Aerosoft A333 pro for P3Dv5 and i cannot get the zip downloads to work in the livery manager the livery manager doesn't show liveries available and there is no readme in the downloads so those that said there are are talking rubbish how is there none when i look then ? so thats wrong for starters on previous posts and i cannot find the folder to manually install liveries. 

i dont know were to install any updated versions of the livery manager neither. would apricate your assistance with this further 

thank you
