QB 2009 Premier

Unfortunately your version is too old and I am not sure you can find the installer file easily. Consider to purchase QB Desktop 2019-2021 with a non subscription license to upgrade your version.

QuickBooks Premier 2009 is a discontinued version that Intuit no longer supports. However, you can still reinstall it as long as you have your original License and Product Number required for activation. Here's the direct download link: QuickBooks Premier 2009 Installer.

Please also note that QuickBooks 2009 may not function properly on modern operating systems. You'll need to install it in a legacy environment for it to work correctly.

Feel free to return if you have follow-up questions.
