Unable to launch IL2 BOS on steam after up grade to Windows 10.

[Vlongo_47]

BOS and IL2 Blitz won't launch via steam. My other games (including IL2 1946) launch perfectly via steam.  I purchased BOS from your store and have the same problem ...won't start. I get this error message:

IL2 exe Bad Image

C;\Windows\SYSTEM32\d3dx11_43.dll is either not designed to run on Windows or it contains an error.

Error status 0xc000012f

Can anyone please tell me how to fix this?

I would like to purchase Flying Circus but expect I will probably have the same issue.

if you bought BOS from the website store (and maybe FC later) I would recommend to use the IL2- Greatest Battles universal launcher, and not the Steam version (you can add the game to the Steam library nonetheless if you with to do so for social functions)
The launcher can be found here https://il2sturmovik.com/download/ and integrates all titles into a single launcher (Steam does treat some titles and content of the current Greatest Battles suite as DLC and there seemingly is a licence key sync issue all the time).

As for Team Fusions rework of "ye 1C of old sans 777 SoW:CoD" - you better contact support.. but be advised... I did that once.. and received a rather puzzling short message many months later.
Since my Blitz boots - from Steam, in WinX (and I have not once played is unfortunately) - I'd recommend to just uninstall it and redownload it via Steam.

Did you ever resolve this issue? I'm suffering the same problem with d3dx11_43.dll apparently being incompatible with my version of Windows. Running the DX web installer doesn't work - it just says that my installation is up to date.

 

Right after posting this I resolved the issue. I renamed the file in the two locations that it existed (X:\Windows\System32 and X:\Windows\SysWOW64) and then ran the dxwebsetup installer. It replaced those two files and now IL2 starts up properly.
