Fix Word 2013 Unsupported Browser Error When Adding Bibcitation
Question details
The user needs to resolve an unsupported browser error that prevents the installation of the Bibcitation add-in.

- Product
- Word 2013
- Device & OS
- Windows 10
- Scenario
- Installing the Bibcitation add-in from Insert > Add-ins > Store.
- Observed behavior
- Word 2013 displays an unsupported-browser message immediately after the user accepts the license terms for the add-in.
Verify that your Windows 10 operating system has all the latest system updates installed, as legacy Office versions rely on core Windows browser components to load the add-in store.
Upgrade Your Office Version
Since Office 2013 is no longer officially supported, upgrading to a modern Office version is the most reliable way to restore add-in functionality.
Microsoft Word 2013 uses outdated embedded browser components (like Internet Explorer 11) to render the Office Store and third-party add-ins. Modern add-ins like Bibcitation require updated browser engines such as Edge WebView2. Because Office 2013 has reached its end of support, it will not receive the updates required to support these newer components.
Open a modern web browser and log into your Microsoft Account to review your current Office licenses.
Select a supported version of Microsoft 365 or a newer standalone Office release that utilizes modern embedded browser architecture.
Download and install the newer Office version on your Windows 10 device, then attempt to install the Bibcitation add-in again via Insert > Add-ins.

Contact the Add-in Developer for Legacy Support
Reach out to the Bibcitation support team to inquire if they offer a legacy version or a standalone application compatible with older Office versions.

Frequently Asked Questions
Why does Word 2013 show an unsupported browser error for add-ins?
Word 2013 relies on older embedded browser technologies, specifically Internet Explorer components, to render add-ins. Most modern add-ins now require newer browser engines (like Edge WebView2) that Word 2013 does not support.
Can I install a new web browser to fix the Word 2013 add-in issue?
No. Installing a new standalone browser like Chrome or Edge will not resolve this issue because Word 2013 is hardcoded to use specific legacy Windows components internally for the Office Store.
Is Microsoft Office 2013 still supported by Microsoft?
No, Microsoft officially ended extended support for Office 2013 on April 11, 2023. The software no longer receives bug fixes, security patches, or updates for modern add-in compatibility.
How can I use Bibcitation if my Office version is unsupported?
You can use the Bibcitation tool directly through their website to generate your citations and bibliographies, then manually copy and paste them into your Word 2013 document.
