EFT isnt installed message, but it is installed

so i bought a new pc and decided to use a external hard drive to copy eft to my new pc so it was faster but now spt-aki says eft isnt installed on my pc, which it is and ive logged into the actual game thinking it needed me to start the game up before it recognized it, but im still getting the same message, so i decided to delete my single player eft and do the process over with downgrading and installing it from scratch, but it still is saying i dont have eft installed, but it clearly is, any idea how I can fix this?

yea i decided to do that and i did factory on offline with bots and extracted and closed the game and went back to my spt-aki folder and started the server and ran the launcher again but as soon as I click start start game, it says eft isnt installed and to buy it to support the makers of it, i also deleted the eft single folder and went back to my live folder and recopied it and downgraded it and reinstalled spt-aki but the same message pops up

im guessing im gonna have to breakdown and just left eft reinstall from scratch and let it do its 2 hour download lol, ill update if that fixes it

ok so that didnt work either, but i decided to try the live again and run a match as a scav and bingo worked, so i guess running you main offline doesnt work, gotta run something online for it to to work
