I may share the installer file for QuickBooks 2005 (i.e Pro, Mac, Enterprise). If you still have the license code and validation code, you can install and open your file on it. Unfortunately your version is too old to migrate to QB Online. Consider purchasing a 3rd party conversion service and you may open it on trial license of Pro 2020. Once you are ready to migrate, make sure you have open your QBO account.
