Using Windows 311 and MSWord 6.0

All of the sudden the formerly good Word 6.0 gets Application Error
Call To Undefined Dynalink. The program will not open.

Checking with First Aid; FA reports Missing dll "winword.dll" is
missing from C:\winword.

Checking my other computers I find no file called winword.dll and
they work.

Idea anybody?
