[ItsClonkAndre]

GTA IV Downgrader

This tool allows users to easily revert their Grand Theft Auto IV installation (versions 1.2.0.30 and up) from Steam or Rockstar Games Launcher to earlier versions such as 1.0.8.0, 1.0.7.0, or 1.0.4.0.

 

Requirements

• .NET Framework 4.8 - Should be installed on every Windows 11/10 machine.
• Windows 11, 10, 8.1, 8 or 7 - Tested on Windows 11, 10 and 7.
• Internet Connection - Only if you dont plan on using the offline mode
• Be in a country which isn't that crappy - Find out why in the " Notes" section.

 

Download most recent version

• IV Downgrader Version 2.2 (5,53 MB) (Mirror)

 

Other downloads

• Downgrading files for manual downgrade

 

Spoiler

THIS IS THE OLD VERSION OF THE IV DOWNGRADER! ONLY USE IF YOU HAVE PROBLEMS WITH THE LATEST ONE!

• GTA IV Downgrader Version 1.7 (1,6 GB)

 

 

How to use

1. Download the Downgrader.
2. Extract the downloaded zip somewhere on your PC but NOT in your GTA IV folder!
3. Run the IVDowngrader.exe file (Preferably as an administrator).
4. Now carefully follow all the steps. That's it!

 

 

Notes

• The downgrader downloads stuff, such as mods and data, from GitHub and Dropbox. Some countries such as Cuba, Iran, North Korea or Syria block these services. So if that's the case for you, you will need to perform a manual downgrade instead.
• The downgrader will NOT delete any of your save files.
• You can savely press "Next" on the "Analysing your GTA IV directory" step if a warning occured. Make sure to read what the warning says tho.
• If an error occurs while the downgrader is trying to download the required downgrading files, you can download them manually here. You can then drag the files you downloaded into the "Data -> Temp" folder of the Downgrader and you can try to redowngrade.

 

 

How to use the downgrader's offline mode ( Only for Version 2.0 and above of the Downgrader )

1. Download the downgrading files you need from here. For example: If you want to downgrade to 1080, and want to use the Legacy Radio Downgrader, you download these 2 files.
2. Place the downloaded files inside the Data -> Temp (If Temp folder doesn't exists, you can just create it) folder of the GTA IV Downgrader. Do not extract the files! Just copy & paste them in there.
3. Run the downgrader using the "LaunchInOfflineMode.exe".
4. The downgrader will now run in offline mode and does not download any file drom the internet. It will only use the files you've put inside the Data > Temp folder.

THIS IS AWESOME!

Oh, good thing I wanted to check if my guide downgrade things are still revelant. I'll update my russian guide with this ASAP. (it hit top 2 russian guides on yearly popularity recently aswell )

UPD: I think you need to fix that, it defaults to French language after the downgrade. I don't think that's what it should do, haha.

So when it comes to the RGL version of the Complete Edition, does this downgrader prevent the launcher from downloading the latest files over and over again every time we launch the game?

You have to move the game folder somewhere else.

When i get to the first step, which is the input of the path of GTAIV.EXE, it says "invalid file - please select GTA IV'S executable file" even though I put the correct path.

When you hover over gtaiv's executable file, what does it say at "File Description"? It should say Grand Theft Auto IV

Other way to check for the File Description is by right clicking on your executable file, then click on Properties, then on Details and there you should see all the details about the exe

Haven't tried it out yet, but looks really awesome! Thank you! Are you, by any chance planning to include the ability to downgrade to other versions, e.g. 1.0.4.0 as well? Would love that.

Thanks! Yes i'm planning on adding the ability to downgrade to 1040 as well!

Ah i fixed it. I needed to just verify the integrity of the game files. However, now the downgrader gets stuck after it says 'Radio Downgrader Finished'

[Guest]

I tried both .net 4.7.2 installed and the downgrader is not opening as well, Windows 7 64 bit.

Tried cat's downgrader as well, stuck on loading complete screen.

Thanks for the information! It should be fixed in the next version! I'll upload it as a hotfix version, so you don't have to download the whole 1,58GB again.

Tested on Windows 7 64 bit aswell and it's working for me.

.NET 4.7.2 was not installed so windows showed me this:

After i installed it, the downgrader worked.

Thanks for info, using 1.2.0.43 version for now. I killed the stuttering though.

Seem to be running into some issues when using the Downgrader; not sure if I just missed something obvious or it's a legitimate issue. Probably the former given my unfamiliarity with modding the game. If I use the radio downgrader options (either by Sneed or Legacy), I get stuck in the downgrading process at the line: "[Radio Downgrader] del install.bat" No error, just hangs.

 

If I skip the radio downgrader, it still states "Extracting files for radio downgrader..." followed by "An error occured... Details: Empty path name is not legal."

 

Fresh install of the game, run once to main menu. Not in a system folder either. Antivirus exclusion is set, Framework is installed. Windows 10.

I've tried both with the files in the zip extracted to the Grand Theft Auto IV folder, outside of the GTAIV folder with game contents, as well as inside of it.

Downgrading to 1.0.7.0. All optional components selected in Step 4.

 

Again, probably my obliviousness causing it, but figured I'd ask for help if anyone has a moment to educate me. Thanks for all the work you've put into the project; looking forward to getting it working on my end and playing soon!

Well, I was right; it was my fault.

Turns out, in my infinite knowledge, I didn't realize that A:\ and B:\ were reserved for floppy disks once upon a time before I used computers, and a year and some change back I installed a new drive and designated it as B:\. Seems like there's an issue with doing so, as the process that deletes install.bat when downgrading the radio can't finish and provides an error stating, "Insert the diskette that contains the batch file and press any key to continue." I didn't see this in the installer, as it displays the process of deleting install.bat, but not the error requesting the diskette to be inserted. Changed my drive letter, issue resolved!

Now to deal with everything else linked to that old drive letter that will inevitably not work... Lesson learned!

[Gillian]

Would you include DXVK/DxWrapper as an optional component in the online downgrader? That'll help some people if you want to make one installer for all the essentialls, to be honest.

An Essentials pack... definitely a consideration for me

Spoiler

Well actually I've already made one in the past but it's not a program, and not everything is up-to-date

My names for my hard drives is : SSD (C:) and HDD (D:). I don't have any A:/ and B:/. My GTAIV folders is in : SSD (C:)/SteamSSD/steamapps/common/Grand Theft Auto IV/GTAIV

[gta sa player]

Is there any difference between the asi loader by AB and the one by thirteenAG? Because if not then I recommend replacing the one with the other and giving it a different name than dsound.dll and then adding DSOAL for the best audio. I would also add these mods:

 

 

Rancher Collision Model Fix
Karin Sultan Trunk Fix
Plane Flight Path Improvements
Fixed Combat Shotgun Icon
Draw Distance Tweak
Controller Button Icon Change (if someone uses a DS3/DS4)
I also recommend reading this guide: How to fix choppiness and stutters in GTA IV

This mod pack's also pretty good.

I think Fusion Fix already includes a fixed Rancher (done in a better way or something) and the Sultan Trunk Fix has messed up vehicle camera.

Why a lot of people seem to face an issue with -availablevidmem in commandline? It keeps setting it at 300mb even though it's set to 2048.0

[LitMan]

I dunno why, but for whatever reason this one does not seem to work for me, but it's also my first time trying to effectively mod GTA IV, so maybe I'm being dumb here. Have tried searching for fix, but no dice.

Installation is not on Program Files (It is, however, in the steamapps folder on my D drive, but I think that's okay?).

The Downgrader itself works fine, no errors, no anything, and it's updated to the most recent version (Hotfix 1), but whenever I press Play, the game just keeps loading infinitely.

If I try to Alt+Tab during it, it'll stop responding. Sometimes it also stops responding after a good 20~30s.

I tried removing save files, adding the commandline.txt arguments to the shortcut, the whole ordeal. Nothing seems to work.

The game runs perfectly fine before the downgrade (whatever version is on steam right now).

I also got a pretty beefy PC, so I doubt it's anything hardware related, or to do with the availablevidmem (I have a RTX 2060 6GB), like so many potential fixes seem to suggest.

 

I did managed to downgrade it using the method described in catsmackaroo's Ultimate GTA IV Setup Guide video, but I figured I might just describe my experience, I have a couple vanilla backups if you'd like me to try anything.
