Before you download
- Windows repairs its own files: run sfc /scannow, then DISM /Online /Cleanup-Image /RestoreHealth in an administrator window, and install the latest update. That is the fix the ucrtbase.dll page recommends.
- Use this copy when a program needs the file in its own folder, or to compare it with yours. It must match your Windows release and build: x86 is for 32-bit programs, on 32-bit and on 64-bit Windows. 64-bit programs need the x64 set.
- Do not copy it into System32 or SysWOW64: Windows protects those folders and the next update replaces the file anyway.
