How do I retrieve DLL file so I can open Microsoft Word

[Kyle Casper]

When I try to open Microsoft Word, A box pops up
saying "Error Starting Program" " A required .DLL file,
WWINTL32.DLL, was not found" How do I retreive this file
so I can open my Microsoft Word 97. I don't have the
software to rerun the program. It's been a while so i
don't know where it is. Is there another way to rerun
Microsoft Word or to find this file? I'm not the most
computer literate person so you'll have to break it down
step by step for me.

Thank you very much,
