Error 1931

[dukec606]

When installing a new program I received the message:
Error 1931, WINNT\System32\mfc42.dll, windows files are
protected may need to update system.

Help - what is it I need to update and how.

installed in your system?
if this isn't right then do a search on
microsoft.com for mfc42.dll
