Are you going to C:\Documents and Settings\username\Application Data\Microsoft\Office\ and right-clicking mso1033.acl, clicking 'send to', and selecting your flash drive?
If yes, are you plugging your flash drive into the other computer (which has the same version of Microsoft Word installed, double clicking 'My computer', selecting your flash drive, right-clicking the mso1033.acl file, clicking 'copy', then going to C:\Documents and Settings\username\Application Data\Microsoft\Office\, right clicking in the office folder, and clicking 'paste'? (You may get a prompt saying "The file mso1033.acl already exists-do you want to replace it?"--click yes)
I don't think you ever need to open the file--
