AKI Release missing files after unzipping

I've been working on getting the installation process to work. I've done everything including reinstalling Tarkov and BSG completely, but I'd always get stuck on the first splash screen. I've tried everything on the FAQ page for that problem, and no dice.

During my most recent reinstall attempt, I was unzipping the AKI files into my pre-made directory, and got an unspecified error. I switched to 7zip, and it extracted fine. This is how it went for the other installs as well. I skipped through the failed files on a whim, and then checked them against the files in the successful 7zip output, and they're all missing. Some notables are language.jsons, several dlls, and while I don't know the extension an AsseblyCSharp file. Could this be what's locking my game's loading up? I don't think the installation is even being completed.

My server throws no errors, the game won't crash, only load forever, and I've redownloaded the AKI files three times and have reproduced this each time. Any Ideas?

Thanks!

Sure:

- I copy the (fresh) live install to a working directory for SPT

- unzip the patcher, patch live copy to x.x.x.17349

- unzip aki v2.3.1, copy/overwrite to SPT directory

when I go to copy the AKI files, many of them fail:

with file explorer unzip, it hard stops with unspecified error 0x08004005

with 7z, it extracts without issue, but is missing the same files explorer said fail. i tested this by 7z unpacking the aki files into a folder and going through them; every file i tested from the error messages was not in the output

I've gone through the install steps a few times now, could I be misinterpreting something?

I yet again redownloaded Tarkov live overnight and did another full reinstall, and by some strange slavic magic the game has magically decided to function normally?

The loading times are a bit longer than vanilla but the game does boot through the splash now. I guess we didn't solve the problem but the effects are gone!
