0xc000001d Error, game crashes upon launch

[Evo]

Hi All,

Whenever I try to launch this game on one my rigs, the green play button goes blue then back to green eventually. I've checked Windows Event Viewer and it gives Exception code: 0xc000001d in the logs for instances of launching this game.

Things I've done to try to fix this:
- Verify file integrity via Steam settings
- Run the command "sfc /scannow" in Powershell as admin
- Run "chkdsk" in Powershell as admin
- Tried both the latest Nvidia Production Branch and Feature Branch Drivers

This rig is very unconventional for gaming since I use it for homelabbing as well, but some brief specs are of the following:

- CPU: Xeon E5-2667 v2 (Ivy Bridge era workstation/server CPU)
- GPU: RTX A4000 (~GeForce RTX 3070 equivalent)
- RAM: 32GB DDR3 (4 x 8GB quad channel)
- Game SSD/Storage: Oracle F320 3.2TB PCIe 3.0 x8 slot
- OS: Windows 11 Pro (24H2 w/all latest updates)

I know the CPU for the rig is ancient, so it's possible that it's missing some newer instruction sets that Square Enix didn't state in the requirements; also, the GPU isn't a typical consumer/gaming one, but a professional/workstation one, so its drivers maybe the issue. Please let me know if yall have any thoughts.

Thanks in advance.

Thanks in advance.

how you installed windows 11 on a CPU that does not got supported by Windows 11 ? Ivy bridge is basicly intel core 2000 series ? this CPU is not supported by Windwos 11.

There has been a workaround since before day one big dog. Windows 11 isn't special.

maybe this work around is not working ? you need Security Boot 2.0 for windows 11 and maybe and just Maybe you wont get 100% support by a workaround.

His CPU isnt even Supporting the game minimum Specs at all, who know's what this game need for specs from the CPU but all i know is this CPU is not supported by Windows 11 Officialy and not supported by the game

Do you just look at specs and thats it? You don't NEED any extra security and it has nothing to do with the issue at hand. Probably the CPU or GPU not supporting an instruction set required.

Funny thing is that this rig is more stable with Windows 11 than my more modern rig which has a Ryzen 5900x and a GeForce RTX 4070Ti; the more modern rig since I upgraded from Windows 10 to Windows 11 about 3 years ago still has this bug in which the file explorer icon in the taskbar still crashes when left clicked the first time on each boot; when I tried to upgrade to 24H2 on that more modern rig recently, it failed installed about 10 times before I used a terminal/command line Microsoft utility to detect residual/incompatible driver files that I had individually delete manually. The "Windows 11 unsupported rig" updated to 24H2 on my first attempt.

Game requires a cpu with AVX2 support. With Intel it started with Haswell (4th Gen) chips. your Ivy Bridge rig only has AVX support.

FF16 has this same requirement/launch failure also btw. I've found out that you can use avx2 emulation to force FF7 Rebirth to play anyway; however, with horrendously slow fps. I'm talking like 5-10 fps with horrible cutscene/menu lag lol. Unfortunately it's not worth it.

That advice was pretty helpful, you are on to something.

So I downloaded the Intel SDE tool and pinned it to an environmental variable.

I decided to emulate a Broadwell CPU and attempted to launch the game with this command in Powershell as admin:

sde -bdw -emu-xinuse 0 -- "path\to\ff7rebirth_.exe"

Game did launch, but took about 3 minutes and my 8 Core/16 Thread Ivy Bridge CPU peaked at around 20% usage; however, it eventually lead to a screen that told me I had to launch the game from the Steam app. Will report back if I make further progress and/or success.

lol nice! Yeah it's the ff7rebirth_ exe that works with the sde. Shader compilation took ages. It's sad games are finally making the jump to using the avx2 instruction set. My oc'd i7-2600k cpu was STRUGGLING to even play the cutscenes that are weaved into the intro gameplay (The first segment with Zack). At best I was only getting around 5 fps, unfortunately.

I've got an axv2 supported cpu & mobo arriving soon, and will deal with ~30fps gameplay on that until I buy modern parts to build a modern rig later on. o7 RIP Sandy Bridge rig (2012 - 2025).

Apparently, there's a mod for this right now:
