Note: This is not yet working. I'm just sharing it here because I thought we might get it running together.


What works:

  • Installation
  • Running Epic Games Launcher
  • Logging in


What doesn't work:

  • Creating an Unreal Engine project (requires Windows 7 SP 1)


Update: Use OpenGL to avoid D3D11 issues (black window). (thanks to Yaakuro for figuring this out)


Update 2: Fixed crash of login window ("Portal") with error

wine: Call from 0x7bc581c0 to unimplemented function WS2_32.dll.InetNtopW, aborting

by adding


to command line arguments.


Update 3: Use 64bit (otherwise you cannot create Unreal Engine projects)


Update 4: Wine 1.9.16 fixes

wine: Call from 0x7bc581c0 to unimplemented function WS2_32.dll.InetNtopW, aborting


Update 5: If the update complains about missing dependencies, try "-SkipBuildPatchPrereq".

Hmmm... Going by this, it might be worthwhile to try adding:

POL_Wine_OverrideDLL "" "d3d11"

Might be worth a try, but don't count on it helping.

This gives me:

err:module:import_dll Library d3d11.dll (which is needed by L"C:\\Program Files\\Epic Games\\Launcher\\Portal\\Binaries\\Win32\\EpicGamesLauncher.exe") not found

I can't say I know what to do in that case. Probably a deficiency in Wine. If there aren't yet any relevent bugs filed on WineHQ bugzilla, though, you could file one about it. A word of warning though: you should retest first with the official wine-staging packages, possibly from the Official Wine PPA if you're running *buntu. Wine isn't exactly friendly about PlayOnLinux, and you should avoid discussing it even though PlayOnLinux uses vanilla Wine. (This is probably due to the fact that PlayOnLinux is very similar to the commercial Crossover, which helps fund Wine development, only free and arguably better.)

I assume it's because D3D11 is not working properly in wine yet. As they are currently working on fixing this (and already have some games running), the near future might bring some improvements.

You can use OpenGL instead of DirectX. Add the  '-OpenGL'  flag as argument. But it still doesn't work. This

wine: Call from 0x7bc581c0 to unimplemented function WS2_32.dll.InetNtopW, aborting

seems to be an issue.

I updated the script. Seems like the argument '-http=wininet' fixes the crash caused by

unimplemented function WS2_32.dll.InetNtopW

I cannot log in but it seems to run in offline mode.

MTres19 Saturday 28 May 2016 at 18:43

Hey, it looks like you're getting somewhere! Try

POL_Call POL_Install_wininet

Maybe that will work!

plata Saturday 28 May 2016 at 19:11

I cannot install wininet. It complains about the checksums.

plata Tuesday 19 July 2016 at 11:46

One more hint: If the Launcher tries to update, it might get stuck in the "Please wait" window. In this case, temporarily remove the "-http=wininet" parameter.

Maybe installing wininet could help but I cannot check this as I said already. Any news on the checksum problem?

(In winetricks the problem has been fixed in the meantime. As MS has removed old files from their servers, they are now using a fallback to to download the required files).

The wine patch solves

wine: Call from 0x7bc581c0 to unimplemented function WS2_32.dll.InetNtopW, aborting

With this patch, also the "-http=wininet" parameter is not needed anymore.

plata Saturday 6 August 2016 at 12:53

Wine 1.9.16 contains the required patch. It is now possible to log in. I can, however, not create an Unreal Engine project because this requires Windows 7 SP1 (if I set Wine to Windows 7, the Launcher does not start anymore - I guess it's the same cef issue as for steamwebhelper).
