mssvcnes.exe isn't a windows file... in fact I can't find much on it at all.
Have you recovered from a recent infection? If yes then it is most likely a start up entry that is looking to run that file. I don't think you will want to re-install it.
Go to start>run and type msconfig then hit OK
click on the startup tab in the window that pops up and check the list and untick mssvcnes.exe if it is there.
