Fix Word 2013 Store Add-ins Unsupported Browser Error
Question details
The user is unable to install modern Store add-ins in Word 2013 due to an error stating that the browser is not supported.
- Product
- Microsoft Word 2013
- Device & OS
- Windows 10
- Scenario
- Attempting to install a Store add-in (such as Bibcitation) and accepting the license terms.
- Observed behavior
- Word blocks the installation and displays a prompt reporting that the underlying browser component is unsupported.
Ensure that your Windows 10 operating system is fully up to date, as Word 2013 relies on legacy system web components to render the Office Store interfaces.
Upgrade to a Supported Microsoft Office Version
Since Word 2013 is no longer officially supported, upgrading to a modern Office version is the most reliable way to meet the browser requirements of modern Store add-ins.
Microsoft Office 2013 has reached the end of its support lifecycle. It relies on outdated Internet Explorer components to load add-ins, which modern add-in developers no longer support. Upgrading resolves these legacy browser dependency issues.
Open Microsoft Word, click on 'File' in the top left corner, and navigate to 'Account' to view your current product details.
Navigate to the official Microsoft website and select a supported version, such as Office 2021 or a Microsoft 365 subscription.
Follow the official download instructions to install the modern suite, then open the new Word application and retry installing your add-ins from the Store.
Contact the Add-in Developer for Alternative Installations
Reach out directly to the add-in developer to check if they offer a legacy version or a standalone installer that bypasses the modern Store requirements.
Try WPS Office for Seamless Document Management
If upgrading your Microsoft Office suite is too costly or complex, consider switching to WPS Office. It is a free, lightweight, and highly compatible alternative that avoids legacy browser dependency errors while keeping your workflow smooth.
- 1. Download the installer: Visit the official WPS Office website and download the free installation package tailored for Windows.
- 2. Install WPS Office: Run the downloaded executable file and follow the straightforward on-screen prompts to complete the setup.
- 3. Open existing documents: Launch WPS Writer and seamlessly open all your previous Word files without encountering legacy browser compatibility blocks.
Frequently Asked Questions
Why does Word 2013 show a 'browser unsupported' error for add-ins?
Word 2013 uses legacy Internet Explorer system components to load the interfaces of Office Store add-ins. Modern add-ins are built using newer web standards that require Edge or WebView2, which Word 2013 cannot utilize.
Can I update Internet Explorer on Windows 10 to fix this add-in error?
No. Windows 10 already includes Internet Explorer 11, which is deprecated. Updating Windows will not change the fact that Word 2013 cannot interface with modern Chromium-based web components required by newer add-ins.
Is it possible to install modern Store add-ins in Word 2013 without upgrading Office?
In most cases, it is not possible. If a specific add-in enforces modern browser protocols, it will block installation on Word 2013. You would need the developer to provide a separate, legacy installer if one is available.
