Bug Fix: Game not opening after January 2024 update

[Gab0Crack31]

Ok, after some time trying various solutions such as logging back into the Rockstar Games launcher without success, I decided to try to repair the game using the "verify integrity of game files" option and after waiting for a while it actually worked . Steam detected errors in some files and started restoring them. Once that process was finished, I tried to open the game and surprisingly it managed to run without many complications. The only problem is that if you downgraded to another version of the game, it will revert to the current version, so I can speculate that if you have some mods installed, they will probably be affected in some way.

for those who have never used the verify integrity of game files option follow this steps:

1. Open your Game Library on Steam

2. Right-click on the GTA IV game

3. Select Properties from the menu

4. In the Properties menu, select 'Local Files' from the left-hand panel

5. On the Local Files page, select 'Verify integrity of game files'

6. Steam will then verify your files. This can take a few minutes, so be patient

I just got back into the game, added fusionfix and a few others on like January 29th and now this ♥♥♥♥ happens when I try to go play lol. Idk why they don't just leave the game alone at this point

Verifying integrity of files allowed me to launch the game, although with none of my mods working. Looks like my 1.0.7.0 GTA 4 executable was updated to 1.2.0.59 in this update.

whenever you got a modded game make sure you set the game to "only update when launched" and if you get an update, backup the game, then update it, then copy the backup over the updated version to keep playing the modded game.

Yep mods are a nightmare to maintain on this game, first you have to downgrade then you have to pray Rockstar doesn't randomly decide to release an update that ♥♥♥♥♥ everything up. I'm gonna try reinstalling the game, downgrading again and reinstalling my mods.

That's advice I always forget lol. Thanks man, verifying was all it took thankfully but I'll definitely watch out in the future.

What method do you use to back it up? My search is giving me varying results on whether or not the mods stay.

To back up the game, for me personally I:

Create a new folder in a known location on a different hard drive specifically for it.
Navigate to the game install folder.
Go back one level (like in Steam the folder you have to click Grand Theft Auto IV then GTA IV. I just copy the main Grand Theft Auto IV folder including the redistributables. Just in case) and just right click copy the entire Grand Theft Auto IV Directory
Navigate to the new hard drive or ssd folder you named like Grand Theft Auto IV Fresh Install or Downgraded version or whatever
Right click, paste. Wait
Backup created.

Problems with current install? Copy the main folders there you saved, navigate to the current main folder that is exactly the same.
Paste.
Try again.
It works


Maybe don't try to launch through Steam though and instead launch through the game folder or send PlayGTAIV.exe to your desktop as a shortcut, then rename it to Grand Theft Auto IV and add an icon to it.

Always launch from that instead of Steam to avoid Steam auto updating stuff and messing up your modded install
