I've embedded a Microsoft Office Spreadsheet 10.0 into a simple MFC dialog using Microsoft Visual Studios .NET (C++). I am running Windows XP, and have Office XP installed, and I have no problem running this application. However, when I send my application to a user running Windows 98 with Office 2000, the dialog will not open, and nothing happens. There are no error messages when the application is run on a separate system than mine, but it does not work. Does anybody have any suggestions or ideas as to why this is happening? Are there other files I should be shipping off with my executable other than the requested .dll's that I'm already sending? Thanks for any help!
