I remember this happened to me one before. One computer was not able to open the file and the other five computers were able to open the file just fine. 

What I did was, I updated it and its works. Dont update from proseries.

You need to go to windows >>> Proseries (what ever year for that file) >>> Proseries updates. Then restart your computer. 

You might want to try that and hope it will work for you.
