1--I can't open this email attachment our Paris office has sent me.
 
2--Are you sure you're using the right program?
 
1-- Well, yes it's definitely the same program but I might have the wrong version.Their system is newer than ours.
 
2-- That's why you can't open it. You'll have to upgrade before you can read the file.
