Just encountered the following error when trying to launch Eclipse SE Desktop:

 

The program can't start because D3DCOMPILER_47.dll is missing from your computer. Try reinstalling the program to fix this problem.

We found the error is caused by D3DCOMPILER_47.dll being removed by a recent Windows update of .NET Framework 4.6.1.

 

Microsoft released a KB for this issue, and has a provided workaround. This happened because Microsoft released a .NET Framework update that removes D3DCompiler_47.dll and prevents .NET Framework 4.7 from installing. This is also the DLL we are missing that SE is trying to use.

 

Microsoft KB (4019990) provides a workaround patch that will re-install the missing DLL file.

Downloading & installing the respective workaround update from Microsoft for your computer should resolve this issue. NOTE: Always check with your IT staff prior to installing Windows Updates.​​​​​​​
