GTA error - ERR_GEN_ZLIB_2

[SamWit]

When I play GTAO it crashes very often. Hell, right now it didn't even start and it crashed. Error box shows up, it says "Failed zlib call. Please reboot, verify the game data, or reinstall the game. For more information, please visit http://rsg.ms/verify". I reinstalled the game twice, verified game files more than 20 times (and steam never found anything wrong) and it keeps crashing. Everytime after verifying when I want to start GTA steam installs social club. Anyone knows what to do? I'm all out of options. Tried installing Social Club remotely, did nothing :/

Open steam / steamapps / common / gtav. Show file extensions.
Delete anything that is NOT a folder AND is NOT a .RPF file.
Exit steam. Disable any antivirus/security software.
Doublecheck there is no gta5/gtavlauncher open in taskmanager/processes. Close if so.
Rightclick steam, run as admin.
Rightclick gtav, properties, local files, verify integrity of game cache.

With steam closed, you can also try deleting the appmanifest_271590.acf - then replace it with the one from this link - trying to skirt around a possible permissions issue/steam not updating certain files that state the game is updated, or constantly forcing SC reinstall. -.-
Once replaced, again - verify cache.

If that doesn't work, there are other instructions in there to fake uninstall/reinstall gtav.
I'd probably check the hdd for errors too.

Did everything except deleting appmanifest, now I'm gonna check if it works.
Can't really tell if it does, because it crashes randomly :F If it works, man, you are my savior.

Zlib "generally" a corrupt file error. Eventhough you've reinstalled/verified cache. The symptom of socialclub always reinstalling says something isn't saving. BECAUSE something isn't saving - its entirely possible the appmanifest is stuck/wrong too. As far as steam is concerned - even if the appmanifest is wrong, the game is right. If updating the appmanifest, and verifying cache again prompts steam to grab more files... it corrected something.

@felkan - That's nice. If it's the same error - the steps are above. If it isn't - start your own thread. Hopefully- you'll attempt to provide more details too. -.- And if that isn't the case -.-

Still crashing... :/

Now the error is called "err sys invalid source 5" but does the same that zlib did.

Then you are up to the link i gave felkan:

Did verify cache actually get forced to download more files after appmanifest replcaement? Did it continue to reinstall social club on restarts?
And- an error change is progress.
(Unless that was error before the reinstalls..)

Are you by any chance overclocking your computer? I had to stop overclocking my i7-3770 after first buying this game because it was causing zlib errors at random.

P.S. in case you don't know, zlib is a file compression library, available to developers at https://www.zlib.net/ which implements the deflate compression algorithm, used in formats like zip, gzip, and png. When the game shows a zlib error it means it detected corruption while decompressing the game assets.

Appmanifest replacement didn't make any new file to download; played for a while, error changed back to zlib one. After verifying game files Social Club still downloads.
