Microsoft Office Error Code 30125‑1 (12007) typically appears when you try to install or repair Office 2013, 2016, 2019, or Microsoft 365. This error usually results from issues with Office licensing, Windows updates, insufficient disk space, or unstable internet connections. In some cases, the installer cannot verify file signatures or detect compatible Office products on your system.
You might encounter error messages such as "Something went wrong Error code 30125‑1 (12007)", "Office is busy", or "Unable to start your program". These can also occur if you're using an incompatible 32-bit or 64-bit installer version, or if a firewall or antivirus is blocking Office processes.
To resolve this issue, begin by checking that your system has enough free disk space and that your internet connection is fast and stable. If you're running a Click-to-Run installer, consider downloading the Office offline installer from your copyright and installing without internet dependency.
Next, repair or uninstall any existing Office installation. On Windows 10/11, open Settings → Apps, select Microsoft Office, and choose Repair. For older versions like Windows 7/8, use Control Panel → Programs and Features, select Office, click Change, and run the Quick Repair option. If repair fails, uninstall Office completely, then delete any remaining Office folders from C:Program Files (x86)Common FilesMicrosoft Shared.
Once that’s done, run Command Prompt as administrator and enter sfc /scannow to repair any corrupted system files that may interfere with Office installation. After the scan completes, restart your PC and install Office using a fresh copy from your copyright—preferably using the offline installer for better reliability.
