How to Fix Office Installation Error Code 30125-1 (12007)
Microsoft Office error code 30125-1 (12007) usually appears during installation when the setup process fails to download necessary files due to connectivity issues or security software interference. To fix this, begin by checking your internet connection to ensure it’s stable and not restricted by a firewall or proxy. Next, temporarily disable any antivirus or firewall software that might be blocking the Office installer. Running the installer as an administrator can also help bypass permission-related interruptions. If the problem persists, try using the offline installer version of Microsoft Office, which can avoid download-related problems. Additionally, running a full system scan with the System File Checker tool (sfc /scannow) may help repair any corrupted system files contributing to the issue.
