I am writing a VB application which uses the Excel
spreadsheet control from the Office web components. My
question is that can I distribute this application without
any restrictions. Should I expect that anybody using this
application has MS Excel installed on his/her PC? Also, do
I have to buy any license or something specifically to
distribute my application? Also, can I ship the required
controls, dlls with my app?

In the worst case, will every work fine if I just ship my
app, and expect the user to have MS Excel installed on
his/her PC with Office Web Components.

Thanks,
