Fix Windows DLLs
the safe, official way.
When Windows complains about msvcp110.dll, d3dx9_43.dll,
or vcruntime140.dll, the right move is not grabbing a
random DLL from a download site. It's installing the matching
Microsoft runtime, running Windows built-in sfc/DISM,
or reinstalling the program from the vendor. We walk you through all three.

The three official safe paths
99% of DLL-missing situations resolve via one of these three.
Install the Microsoft runtime
VC++ Redistributable, DirectX End-User Runtime, .NET Framework are all distributed by Microsoft β signed, trusted, and maintained.
Open Microsoft Learn βRun Windows built-in tools
System File Checker sfc /scannow and Deployment Image Servicing DISM /Online /Cleanup-Image /RestoreHealth repair the vast majority of system DLLs.
Reinstall the affected program
