Battlefield Anti-cheat refuses to install

After trying several solutions for an hour and a half, the problem was finally resolved.
Here are the steps that were taken :

Complete restoration of EA Anticheat (With a file from my own PC to force the uninstallation of EAAantiCheat)
I tried the manual method, but it didn't work, so I did everything using the repair tool.

EAAntiCheat.GameService.dll
EAAntiCheat.GameService.exe
EAAntiCheat.Installer.exe
---------------------------------
- RESULT BEFORE RESTORATION -
Event log -> Failed retrieving service path

EAAntiCheat.exe ->
ResourceExtract failed:1113
Install failed:701
-------------------------------
Forcing activation of the EAAntiCheat service
(I didn't need to uninstall it because it wouldn't install with the user files)

sc create EAAntiCheatService binPath= "C:\Program Files\EA\AC\EAAntiCheat.GameService.exe" start= auto

Testing :

sc start EAAntiCheatService
sc query EAAntiCheatService

After that launch EAAntiCheat.Installer to uninstall completely

---------------------------------
- RESULT AFTER RESTORATION -
Event log -> No more error

CertificateUninstall success
Uninstall success
-------------------------------
