In my program, when the user selects a particular menuitem, Word opens up and display the file. Under project,reference I checked Microsoft Word 9.0 object library and it runs in Word 2000. My friend has an older version of Word, and therefore it crashes when he selects that menuitem when running the exe. How can I go to his project, reference and check MS Word 8.0 object library so he can run the exe? Thanks.
