I Have 2 questions first i have version 1.7.3 where do i put the hyperedit file? and also i have all of the dlcs i don't know if it will conflict the files. second when i am in the VAB Or The Spaceplane hanger the parts appear to be blue but when i place then its normal please help me!

Use Twitch to download mods and it automatically places the files in the right place.
