Check administrator permissions

In most cases, error 30183-27 is related to insufficient permissions. Make sure you run the installer as an administrator:

• Right-click the installer icon and select "Run as administrator".
• If it is an installer downloaded through a browser, please find the downloaded file (usually setup.exe ), right-click "Properties", check whether it is marked as restricted, and uncheck the "Unlock" option (if it exists).
• Make sure the currently logged in Windows account has administrator privileges.

If you are installing on a corporate network or restricted environment, you may need to contact the IT department for higher permissions.

Clean up temporary files and caches

• Delete all files in this directory (if there are any files that cannot be deleted, just skip them).
• Open the run window again, enter temp , and clean another temporary folder.
• Similarly, enter C:\Users\你的用户名\AppData\Local\Temp and clean it up.

In addition, you can try running the disk cleanup tool to free up more space to avoid installation failures due to insufficient disk space.

Turn off third-party security software

Some antivirus software or firewalls may prevent the Office installer from modifying system files, causing an error.

• Temporarily disable antivirus software or firewalls (such as Windows Defender, Kaspersky, Tortuguese, etc.).
• If there are multiple security software, it is recommended to check them one by one.
• Remember to re-enable the protection function after the installation is completed.
