- Observed behavior
- The installation process is interrupted and fails, displaying error code 30015-11 due to residual files or system corruption.

Run the Microsoft Office Uninstall Support Tool

Double-click the downloaded executable file and follow the on-screen prompts to install and launch the tool.
In the application window, select 'Office 2019' from the list of installed products and click 'Next' to begin the deep clean process.
Once the tool confirms the removal is complete, restart your Windows computer. After rebooting, run the Office 2019 installer again.
