Titanfall 2 installed on steam but EA wont detect it being installed

I bought Titanfall 2 on origin after having moved over to PC from PS4, and I've had the origin version of the game installed ever since. I've since bought the game again on steam in the hopes of not having to interact with EA's launchers. I went through my files today because I realized that after origin was replaced by their new EA launcher, Steam wasn't tracking my playtime after I get sent through the EA Launcher. I found my old Origin install of the game, and deleted it to save some space. But now I can't launch the game from Steam, as when I get redirected to the EA Launcher it tells me that I don't have the game installed. I have other Origin/EA games on Steam, notably, Plants vs Zombies GW2, and it launces and runs just fine. I believe this is because the EA app doesn't recognize that I own the Steam version of Titanfall 2, as the game on the EA Launcher doesn't have the Steam logo in the top left corner, but it still tracks DLC-packs I've bought for the game on Steam. I have the Steam version of the game installed, and I am able to run it just fine with the use of the Northstar Launcher, but I can't seem to play on the official servers without downloading a separate but identical version of the game just to make the EA Launcher happy.

I would like to play on my years old save, and on the official servers with friends who don't want to go through Northstar, but I don't want to have to download two different versions of the same game. Either a way to make the EA app check (because I have my EA and Steam accounts linked). Or, preferably, to remove the EA infrastructure from the equation and make Titanfall -and the other games available after the hail mary to move back to Steam- execute straight from Steam, like with Apex, would be appreciated.

A sarcastic thanks to the ones behind the decision to create- and those behind the upkeep of the EA Launchers.

And a sincere thanks to anyone who comes with a fix to my issue.

I bought Titanfall 2 Ultimate edition on steam due to September sale however till not i am unable to play even a single second due to this stupid error saying game not installed on EA, i have the game on steam.

I have tried lots of solutions but there is no hope as of one, if anyone figured out how to fix this, please let me know

I have attached a screenshot of the error. this is really disappointing from EA why cant it be like apex that it launches through steam directly instead of forcing the EA application and showing this error constantly.

не, проблема точно не в этом. Я ранее не имел игры на акке и все равно эти ебучие сервера на работают. Потому что игра ищет Origin, который убрали, а добавить новый EA не смогли.

have you found a way to fix this 

It won't let me connect my account to EA..

Alright, I did some digging on my own, as the methods posed by the EA official still didn't work for me.

I came by a Steam discussion post which used a different method.

I'll leave the link here:
https://steamcommunity.com/app/1237970/discussions/0/6792046983690901877/

For those who don't want to go through the hassle of the single mouseclick on the link I'll retread the process.

1.) Click on your Windows Search Bar (or just press the Windows Key) and type in "Registry Editor".

2.) Open the program.

3.) Navigate to the Titanfall 2 registry by opening (doubleclicking) these filepaths in the editor: HKEY_LOCAL_MACHINE > SOFTWARE > Respawn > Titanfall 2.

4.) Double click "Install Dir".

This window might seem a bit confusing, but that's okay, as you don't need to understand it.

It should show a list reminiscent of this:

(Default) REG_SZ (value not set)
displayname REG_SZ Titanfall 2
Install Dir REG_SZ {*File Directory*}
locale REG_SZ en_US *your language chosen*
Product GUID REG_SZ {numbers}

5.) What you want to change here is the File Directory, if you're struggling with the titular issue it probably points towards an origin install of Titanfall 2.

Highlight the origin filepaht and copypaste your Steamapps install of Titanfall 2. (pic attached)

By launching Titanfall 2 on Steam now the EA App should recognise you ownership of the game on steam, and the issue is no more.

If this didn't work for you, I'm sorry, but it now does for me, and I'm way too exhausted by this to care for it any further.

I wish you all luck on the battlefield.

Godspeed pilots, happy hunting, and prepare for Titanfall.
