(Redirected) Is my brand new XPS 2720 with Windows 8.1 missing essential sytem files?

I launched Windows Speech Recognition only to receive following error message:

cspNotify sapisvr.exe

This programme cannot start becasue the following file is missing from your computer:  api-ms-win-crt-heap-I1-1-0.dll

Is this a file installed with Windows 8.1 file?  It appears to be if Windows Speech Recognition depends on it.  If so why is it missing from my computer?

How can I remedy?  Would I need to (re)install Speech Recognition?  How can I do this if Dell do not ship copy of Windows CD with their system? Can Iinstall this from the hidden partitions or system recovery somewhow?

Can I simply install the missing dll file instead?

Please help.
