0024:warn:dxdiag:IDxDiagProviderImpl_QueryInterface (001598E8)->({7d0f462f-4064-4862-bc7f-933e5058c10e},01037FF4),not found
It queries 7d0f462f-4064-4862-bc7f-933e5058c10e in IDxDiagProvider::QueryInterface(). This IID looks like IID_IDxDiagContainer, but the end is different. Returning IDxDiagContainer makes it crash. I tried looking for a definition, but can't find one anywhere.
It seems this is a probably a private Microsoft interface, so not sure what could be done about this.
That's a red herring/different issue (likely one that shows up when viewing the full report, which shows missing registry entries, etc.).
The 'DirectX Files' check simply looks for the dlls in system32 (and their version info) (already tested).
