How to Fix Office Error 30183-27 When Changing the Default Language
Question details
The user needs to resolve error code 30183-27 (400) which occurs when trying to set English as the default language or when installing a language accessory pack.
- Product
- Microsoft Office (Microsoft 365, Office 2021, Word, Excel)
- Device & OS
- not provided
- Scenario
- Attempting to change the default display or authoring language in Microsoft Office applications.
- Observed behavior
- The language pack installation fails or the language change is rejected, displaying the error code 30183-27 (400).
Ensure that you have a stable internet connection and that all Microsoft Office applications (Word, Excel, Outlook, etc.) are completely closed before attempting to reinstall or repair language packs.
Remove and Reinstall the Language Accessory Pack
This is the most common fix for language pack conflicts. By completely removing the corrupted pack and downloading a fresh copy, you can bypass the installation error.
Often, language pack errors occur due to version mismatches or corrupted download files. Checking your exact Office version and downloading the corresponding pack directly from Microsoft resolves this.
Open Excel or Word, click on 'File', and select 'Account'. Note the version and build number under the 'Product Information' section.
Open your computer's Settings, go to 'Apps' > 'Installed apps' (or 'Programs and Features' in Control Panel), find the English language pack for Microsoft Office, and click 'Uninstall'.
Navigate to the official Microsoft Language Accessory Pack page in your web browser. Select your specific Office version and download the English pack.
Run the downloaded executable file. Once installed, open Excel, go to 'File' > 'Options' > 'Language', and set English as your default display and authoring language.
Perform an Online Repair of Office
Use this solution if reinstalling the language pack alone does not fix the error, as there may be deeper corruption within the Office installation files.
Completely Reinstall Microsoft 365
If both reinstalling the pack and running a repair fail, a complete reinstallation of the Office suite ensures all underlying registry errors causing 30183-27 are eliminated.

Frequently Asked Questions
Why am I getting error 30183-27 when changing my Office language?
Error 30183-27 typically occurs due to corrupted installation files, poor internet connectivity during the download of a language accessory pack, or a mismatch between the version of the downloaded language pack and your installed Office suite.
Can I install an Office language pack if my PC is managed by my workplace?
Often, you cannot. If your device or Office 365 subscription is managed by an enterprise IT department, administrative restrictions may block you from installing external packages. You will need to contact your IT administrator to deploy the language pack for you.
Does performing an Online Repair delete my Word or Excel files?
No. Running an Online Repair or a Quick Repair for Microsoft Office only scans and replaces the application's core program files and registry keys. It will not delete, move, or modify any of your personal documents or spreadsheets.
Where can I find the correct Microsoft Language Accessory Pack?
You can find the official Language Accessory Packs directly on Microsoft's support website. Ensure you select the tab that matches your specific version of Office (such as Microsoft 365, Office 2021, or Office 2019) to avoid compatibility errors.
