cant download the game

Okay thats fine just skip to the next part, because it has not downloaded idk what files are left on the system.

one of my other games uses anti cheat if I delete it will it effect my other games?

No, you can just repair the game and it will pop back up if you have any issues

if it does effect other games how do I repair it?

As i said you just repair the game your having the issue with.

Ive removed the EAC from Apex before and the game simply wont load.

You simply just repair the game to restore it.

If the EAC is with the game files of the other game it should not affect it.

EDIT: sorry, you right click the game in origin and click repair.

there is no appdata in my c:\users file

also one of my other games since I deleted anti cheat does not work this is slightly worrying me as this is my favourite game.

alssoooo (again) I have followed all the steps but it wont go past 40% and it says 0 minutes 0 hours left

Hmm have you downloaded Apex game files in a non default location?

I think so because it said I couldnt
