Error code 30125‑1 (12007) in Office typically indicates that the installer is unable to download or access required files, often due to network issues, system settings, or conflicts with other software. To resolve it efficiently, follow these steps:

• Restart your computer and close any Office-related processes using Task Manager.


• Ensure your internet connection is stable and not blocked by network restrictions or proxy settings.


• Temporarily disable any firewall or third-party antivirus programs that may be interfering with Office’s download.


• Run the Office installer as an administrator by right-clicking the setup executable and selecting “Run as administrator.”


• If you're using a VPN or proxy, disable it temporarily and attempt the installation again—these can block Office from reaching Microsoft servers.


• Use the Microsoft Support and Recovery Assistant to automatically detect and correct download and installation issues.


• As a last resort, download the offline installer (ISO or MSI package) from your copyright and install Office without requiring an online connection.
