Windows 7 Support + EXCEPTION_ACCESS_VIOLATION Error + Crash Report

[.:\-WizmaN-/:.]

Did Windows 7 support get dropped? I am running into an error upon launching the demo version of the game. It's crashing before even launching. I have closed MSI Afterburner and Rivatuner Statistics Server (RTSS), as well as disabled Steam Overlay, Discord Overlay, and any other related game overlays. I have also tried enabling compatibility mode for Windows 7 on the DungeonCrawler.exe file. The issue still remains.

In the past, I was able to launch the game during all of the past playtests and played the game perfectly with my friends. That said, has Windows 7 support been officially dropped due to new Epic Games Launcher (EGS) or Unreal Engine 5 (UE5) integration(s)? Will a fix be implemented soon to resolve the crashing?

Here's the crash report that I am receiving when launching the game:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000000

Thank you very much to anyone that can help provide an answer to my question.

It runs on Unreal Engine 5 now, which does not support Windows 7.

That makes a lot of sense. I will have to use a dual-boot installation of Windows 10 in order to play Dark and Darker now. Thank you, Wilde.

Edit: To anyone else reading this post, the system requirements of Unreal Engine 5 (UE5) can be found here: https://docs.unrealengine.com/5.0/en-US/hardware-and-software-specifications-for-unreal-engine/

I don't think that's a good indicator. My girlfriend uses Windows 8.1 and yet shes able to run this game just fine.

Both the December Playtest and the new February Demo use the same UE5 5.0.3 version. Yet the Playtest ran fine and the Demo is now crashing. The only difference, that I can see at a glance, is the new version is now loading some extra TencentGME junk....

I think I saw people here running it on Windows 7.
You can try to disable background processes - especially Rivatuner and MSI Afterburner.

Windows 7 is a dead OS. Upgrade your potato.

The minimum software requirements for Unreal Engine 5 are subdivided into two; requirements for running the engine and requirements for editing the engine. For Running the engine, the minimum operating system requirement is Windows 10.

To anyone reading this, with the latest hotfix #2 patch, the option of running DirectX 11 (DX11) rather than DX12 is now possible again! DX11 is supported by Windows 7 and should allow the game to run now!! I will have to test this and make sure it works, though I'm 90% sure this was the cause of it not running this playtest! Thank you devs for re-enabling DX11 support!!

Solution: Choose DirectX 11 when launching the game and it should work!!

[.:\-WizmaN-/:.]

Add the "-dx11" or "-d3d11" or "-force-d3d11" parameter (without quotation marks) to the game's Launch Options within the Steam Library game properties window. The first parameter should do the trick. Let me know if that works!!

Edit: The latest hotfix #2 patch notes can be read here with regards to the DirectX 11 changes: https://store.steampowered.com/news/app/2016590/view/3640633392759301422?l=english

Just downloaded the update. Seems it still isn't solving the issue.

it doest work
i have windows 7, like everyone has been telling you UE5 doesnt support windows 7, even if you have dx11, because its running from UE5 engie it disables windows 7

The previous playtest was using UE5 as well and windows 7 players could use it just fine. Also, my gf uses windows 8.1 and it works without issue on her computer.
