After many wasted years, I was able to find a solution. Download the version we need here https://hub.sp-tarkov.com/file…204-aki-patcher/#versions. We then rename it to "patcher".
Download the installer here SPT-AKI-INSTALLER. We run the installer, if it gives an error, it's okay, this will help us so that the cache folder appears in the appdata folder. After that, transfer the zip file along the path C:\Users\name\AppData\Roaming\spt-installer\cache.
MANDATORY WITH REPLACEMENT OF FILES. Then we launch the installer and rejoice.
I could not install it manually because there were also problems that I could not solve.
This worked, thanks
