Possible build project with UE 4.25 on Windows 7?

Development Programming & Scripting
1

Good afternoon, I would like to know whether the ability to build the project using UE 4.25 of Windows 7 is still preserved? Just when starting any project built on UE 4.25 on Windows 7, an error with createdxgifactory2 and dhgi comes out. Googling found this page here CreateDXGIFactory2 function (dxgi1_3.h) - Win32 apps | Microsoft Docs . On which it is written that this function exists only on Win 8.1 and above. So it turns out that no more projects can be assembled under Win7 on UE 4.25.

Had the same issue. Got a fix, but most of you won’t like it. You have to:

  1. Build the engine from source yourself.
  2. Have access to Epic’s P4 Main branch (tricky, most indies don’t have Epic’s P4 at all afaik, non-devs definitely not) OR access to Epic’s github (this is easier, requires just creating several accounts and linking them).

P4: Check the latest commits in the Engine/Source/Runtime/Windows/D3D11RHI folder. The fix was made before this thread even started, on 2nd of June. There are 2 separate commits that when both merged and built resolve the issue.

Github: Here are the links (they will work only if you are logged in and have properly set up the accounts, otherwise you will see error 404):

https://github.com/EpicGames/UnrealEngine/commit/108d0d50f4c394cb2f8a2bf0e9f2052dde4c42e3
https://github.com/EpicGames/UnrealEngine/commit/31d7cf99c275e5c13761542fe459f5db7a91f2f9

You can merge them, or just do the same thing in the source if it’s hard for you to merge from github.

If you have blueprint project - you’re not fixing this.
If you do not build from source and use launcher only - you’re not fixing this.

As far as I can see, those fixes are not merged from Master (or Main in P4 naming convention) into 4.25 or 4.25Plus, so there is no hotfix coming with this change. Especially considering that the fix is on the master for 21 days without a merge.

Hope this helps at least somebody.

Ou, thank you!) Waiting fixes and there you will see whether they merge changes or not.

Hi guys, this is now fixed on 4.25.2 with perforce changelist 13865439. Might take a couple of hours to populate on github. Apologies for the issues!

When is this expected to go live to the Epic Launcher for those that dont do source compiles?
