Software on my computer that uses the .NET Framework (PAINT.NET and the Visual Studio 2017 installer) is crashing on start up with the error message:

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

Despite having Service Pack 1 installed, when I try to install KB4019990 (as per this article), I get the error:

The update is not applicable to your computer.

Note:

  • I first discovered the problem in September when trying to run PAINT.NET, but I only attempted to fix it with KB4019990 on the 5th of November.
  • One thing that could be relevant is that the installation of KB4041681 failed and is not listed as being installed. This update, however, was after when I first discovered the issue.
  • I managed to fix the issue with PAINT.NET by finding an old version of d3dcompiler_47.dll on my computer and copying it into the PAINT.NET install directory.
  • I do not have any copies (old or new) of d3dcompiler_47.dll under %windir%\system32\
  • 1
    You are sure neither of these updates have been superceeded by another update. Service Pack 1 was released years ago. What is the file version of this file. Patches are strange if the file being updated isn’t a match then it could be blocking the update – Ramhound Nov 9 '17 at 21:52
  • I don't think KB4019990 has been superceeded as this link does not list any patches as replacing it for Windows 7 x64. According to this no updates replace KB4041681 for Windows 7 x64. The random version of d3dcompiler_47.dll I found on my computer is version 6.3.9600.16428. Should I copy the random copy of the file into %windir%\system32\ and then try to install either KB4041681 or reinstall a previous update that was supposed to update this file? – James Nov 10 '17 at 9:25
  • I am pretty sure the current version of the file before the patch is 6.3.9600.18611 because it should have a date of April 2017 and the file version will be something else after the patch your trying to install. – Ramhound Nov 10 '17 at 12:54
  • I've checked all versions of d3dcompiler.dll on my computer and none are 6.3.9600.18611. Should I get a copy of d3dcompiler.dll from a friend who has Windows 7? – James Nov 11 '17 at 0:57
