Normally, when the progress bar disappears, the installation is almost complete. Near the end, you may see a message that you can start using the Office apps.
Do you see any error messages at some stage during the attempted install? Installing Office may be a slow process, especially under Windows. No messages (no errors and no other types of messages) may indicate that everything went smoothly.
