ZClient BF3 Unknown exe file

my problem is.. everytime i join for a server for the first time it works normaly without any problems,but the problem comes when i shut down the launcher.
when i try to join a server again or even by clicking 'Run game' in ZClient it shows the error 'Unknown exe file'.
i`ve tried to join through the servers list in 'zloemu.net', same problem.
but i got a solution(not real Solution).
reinstalling the game will make it work,but you will still face this problem after exiting from your first match or even after restarting your pc.
i dont know why this happining and how to fix that bcz i didnt like this solution as its soo annoying that u have to reinstall the game everytime to just play multiplayer(yeah u can play offline but not through the launcher).
i dont know if this an individual problem, but i dont think so
as i saw another guys facing this problem but never find the answer.
 

so if any one could help please reply.

Note: Game downloaded through 'zloemu.net' torrent method.

ZOrigin is normaly shows the game
but when click on play nothing happen

can i manually set the game path for Zlorigin ? maybe this will solve the problem idk.

NVM.
I`ve found the solution for this.

for anyone facing this problem and still wanna fix it
here is how to:

1- run ZClient

2- Click on Run ZLOrigin

3- Find Your Game(For me its bf3)

4 - Right click on it 

5- Click on Repair Game

Thats all.. u will have to wait untill it finish then start ur game!

Real problem is something changes exe on your pc, maybe virus, thats why file is unknown.

Actually windows defender is disabled and no anti virus enabled, also nothing is changing in game files/exe.

but thx for your reply.
