How to fix a missing DirectX DLL in Windows Server 2022?

Question

I have a server setup running Win Server 2022 that I'm attempting to run a server program. The issue that is occurring is that this particular program is looking for D3DCompiler_43.dll from DirectX. I found that there is the D3DCompiler_47.dll in the system32 and SysWOW64 folders. I have tried some different ways to add this dll like using regsvr32 d3dcompiler_43.dll, but only to have an error of "The module "d3dcompiler_43" was loaded but the entry-point DllRegisterServer was not found". Is there a way to get this added? Or am I out of luck on this missing dll?

Answer 1

On my Win11 laptop I found 2 instances of that dll.

C:\>dir D3DCompiler_43* /b /s
C:\Program Files (x86)\Quicken\d3dcompiler_43.dll
C:\Program Files (x86)\Quicken\ScreenShare\d3dcompiler_43.dll

These dlls are part of the Quicken install, so when you ran the install for whatever software you are executing it should have copied that dll into the application's Program Files folder.

If you just copied the executable and didn't run the .msi installation, then you could try copying that dll into the directory where the .exe is. But you might be missing other dlls.

I did not find that dll referenced anywhere in the registry.

Hello

This may happen when there are some dll file missing, and the error will show looking for the related .dll file.

Firstly try find a same version, good working machine in the same environment, then locate the dll file on that machine, copy and replace it to current good-working machine.

If the manual fix still fails, try use a source file to do restorehealth:

In the same network environment, find another same and good-working system, find C:\Windows\WinSXS, right-click this folder and share the network path, such as

On the problematic machine, run the following command to repair the damage in our specified source. Note, replace the drive number with the drive number mapped on the computer.

Dism /Online /Cleanup-Image /RestoreHealth /Source:{source file location}
