The exact reason for that error message is that your Windows is missing a file "ucrtbase.dll", 32-bit version of it. If you have 64-bit OS, it should be in %WINDOWS%\SysWOW64 folder. Otherwise it's in %WINDOWS%\System32 folder. On Windows 10 the file should always be there. For older Windows versions, the KB2999226 will install it.
If the KB won't install, one option it to manually copy the file there from another Windows computer.

there's also a command
DISM /Online /Cleanup-Image /Scanhealth
that can be run as admin to scan your operating system for corruption given new enough Windows (this is essentially a case of operating-system-level corruption) assuming you picked the installer for right operating system.
