@Epix At first I had zero interest to spawn the new DLC because I only use addon vehicles for cars (with a few exceptions such as the insurgent).
So many people were having this problem and at least 2 or 3 said they easily succeeded that I decided to try myself.
I followed their steps, launched GTA5 with all my mods, and tried 3 different ways (Menyoo, addon vehicle spawner mod, and c# with LemonUI) to spawn.
Either nothing happened (C#) or Invalid Model (Menyoo), or "Wrong version of GTA" from addon vehicle spawner because it correctly saw I had downgraded GTA5.exe to bypass the SHV that no longer works.

So I verified all my steps. Went into OpenIV.
Were the DLCs there? Yep.
Could I see the vehicles like Euros? Yep.
Was my dlclist.xml updated for MPTUNER without syntax errors (after about 300 manual entries, I think have the process down).

Next I experimented, Steam Version. Only constant was that GTA5.exe had to be the previous version - if not, no Mods.
I basically tried every combination, and they are limited, and nothing worked. Either game would hang during launch, or launch but not allow spawns.

In summary I tried.

The steps that those who had succeeded posted. Having MPTUNER also in my mods folder Downgrading my mods version of Update.rpf Upgrading my mods version of Update.rpf Downgrading my mods version of Update.rpf but adding MPTUNER, then downgrading game version of Update.rpf Made sure my gameconfig was properly loaded in Mods (each attempt) Tried with a lighter version of my dlcpacks A few more combos which I know probably didn't make sense out of desperation.

Conclusion: I can't do this on my setup. Likely something is conflicting. My setup is highly customized and tweaked with many edits, a custom ped addon process which I created, etc. So my game is definitely full of variables.

Anyway, as I said before have no interest in this DLC but was hoping to create a tutorial - that won't happen.

@finsikesi64 Great news for you. Go into your GTA5 installation folder, also called the root folder.

In there you will see a file called dinput8.dll (microsoft direct input).

Temporarily rename this file anything you want. For example rename it with a dot at the beginning, .dinput8.dll (will be easy to find) or dinput8.bak - whatever you want.
Start your online game. That's it. Next time you want to play SP, just rename it back to the correct dinput8.dll name.

Want to do this automatically, create a batch file that renames and then launches GTAV.

What happens with Steam (not sure about Epic) if you forget to do this and accidentally try to go online. Your game will be deleted automatically and you will be banned for life. Ok, just kidding. Nothing will happen. You will simply get a warning that you are trying to go online with a modded game.

So rest easy. No need for duplicate games. One file renamed. That's it. That's all.

an easier way to uninstall it instead of just deleting the mods folder is update/x64/dlcpacks/ Delete CW, then go to dlclist.xml and delete the cw code

@GTA-V-Gaming La réinstallation de GTA ne désinstallera pas vos mods. Avez-vous désinstallé tous les mods (il vous suffit de renommer dinput8.dll temporairement pour arrêter tous les mods)

@QuangDuKich That's a custom wrap. Why not put your post in the request forum, but I doubt anyone will reproduce a texture like that.

@JesonMile The only thing you will do with 2 version of GTA5 is use up disk space for nothing.
The whole GTA5 modding process was created to support both versions - modded for SP and un modded for GTAO and SP.
All you need to do, despite what you might read on other threads, is to rename dinput8.dll temporarily and GTA5 will completely ignore 100% of all your mods.
If you find that annoying, create 2 powershell or command prompt batch files that will rename for you and then launch your desired choice.
I use batch files like this myself, and even batch files that allow me to enable or disable mega mods for more stability.

Actually I have 3 versions of GTA5, without really installing 3 versions - by having 2 dlcpack folders.

Un modded GTA 5 by renaming dinput8.dll Modded GTA 5 with all my addons (I named it DlcpacksFull) Modded GTA 5 with only key addons for best performance (I named it DlcpacksLite)

I switch between 2 and 3 simply by having a second dlcpacks folder with minimal addons - so very little disk space wasted.
I just rename the one I want to play with as dlcpacks and that's it. Don't need to change dlclist.xml or any other files. Dlclist will not cause any system issues if an addon is listed but not installed (except if you refer to it in a script ofc).

@TwixFroGGer Do you have ENB installed as well? If so check bloom settings. Did you download NVE from Razed patreon? If so, you should have access to his discord and can ask him directly. He would be your best option for any issues or setting adjustments with NVE.

@DAIVIK2629 If you want to change into your addon peds using your controller, download simple trainer, and add the addon peds into the trainerv.ini and then when you use your trainer, go to peds, then addon peds, and select you addon ped. Note: make sure the name of the addon ped is the same in the trainer and the addon folder. Example; the file is batman.ytd, so when you go to the trainer you would name it just batman.

@Tato-Motero GTA V was updated today. Mods don't work as of right now. ScripthookV needs to be updated. Please be patient and wait for an update in the coming days to about a week.

@JohnFromGWN Ok d'accord merci infiniment 🙏

@JohnFromGWN hi I am new to this gtav mods. is my first time i use that video that you recommended. but when I press f8 on the game nothing pop up. I downloaded
open iv then the mod menyoo pc 1.4.0, didi noth work so i dowloded the Script Hook V like the video says. but no mod menu F8

@Wairted With that system you really don't need those mods. I've tried them and uninstalled them in 10 minutes. They remind me of amateur photographers who take crap pictures and then play around in Photoshop boosting the contrast, increasing the saturation, adding filters - and then thinking their crap is a masterpiece. I have system with lower specs than you (32 GB ram, Ryzen 9 3900X , RTX 2070 Super 8GB) and my graphics are beautiful, maxed out and 60 FPS (limited by my monitor's refresh rate) - with 200 addons or more.

@LorissiroL said in Car Not Spawn:

ho installato "addon car spawner", rispettivamente nel percorso file di gta5.
e prima che li leggessi nel tuo commento non avevo mai nemmeno sentito parlare di file di configuratore e regolatori di heap, puoi spiegarmi meglio cosa sono e a cosa servono ?

Questi file ti consentono di avere più veicoli o solo più componenti aggiuntivi, quindi il gioco normalmente consente. Può bastare una sola macchina per mandare in crash un sistema senza un gameconfig o un aggiustatore di heap, anche con un sistema di fascia alta con molta memoria e memoria video.

Thanks after verifying my game ran successfully

@ItsJustCurtis hahaha yes! This was my issue. smh i should've known this. thanks for the help man.

@JohnFromGWN at first, i thought add-on cars were kinda hard to figure out how to install them, that was years ago when i first started modding gta 5, but now i do it like its nothing, not really that hard, common sense tbh lol

@Emerald-Mustang
Yep, sounds like a ModKitID conflict. Refer to post#2 or search internet for info

@oliver_30 I'm not surprised, stuff happens.
This is what i would suggest.

Verify the integrity of your files. Rename the file dinput8.dll in your installation/root folder to something else, for example dinput8.bak

The first suggestion will rule out any corrupt files, which is probably unlikely but worth doing.
The second suggestion is to see if the game will run without mods, without having to uninstall any.

Another possibility, which I went through myself, is a corrupt save game file (not fixed or flagged by verify integrity) - but start with the first two.

@heliosick I'm glad. Thanks for letting us know it worked out.

@Jensen0812 Very likely because your installation went wrong (cause and effect). Uninstall all 3 and install one by one, checking if your game will launch properly.

What isn't clear is what "will not even work" mean. Do you get an error message, hangs on load, crashes to desktop, etc. Each issue has a separate solution potentially.

You might not even need the packfile limiter depending on which gameconfig (limitless vehicles - actually that's quite funny) you use.
The heapadjuster goes in your installation/root folder so you might want to install that first and I would further suggest if you do that to rename your mods folder temporarily so that no mods load. If the game then starts, rename mods back to mod and install the gameconfig.

If you are using Steam and a mods folder, correct path in OpenIV will be something like:
MyDriveLetter:\SteamLibrary\steamapps\common\Grand Theft Auto V*mods\update\update.rpf\common\data*

Only important part is the bolded part because you might be on another path or using R*/Epic.

@MrSleeperMobile That's because you're not extracting using the proper option.

Strongly recommend you use this free/opensource extractor
https://www.7-zip.org/download.html

Once installed, you can extract zip, rar, whatever archive, even OIV.
You right click the zipped/archive folder, and from the 7-Zip menu select "extract to [name of folder/"

For example you downloaded an addon called ferrari.zip or ferrari.rar.
Rightclick the file, from the context menu select, 7-Zip, from that menu select "extract to ferrari/"

If you don't want to install 7-Zip, then you will likely find a comparable option with other software.
For example, with Windows 10 and a zip file, just do Extract All and it will be on neat package.
Always try to extract to a folder, if it just says "Extract here" you'll get the files out of the folder - in other words all over the place.
