In other cases, users might be directed into restarting their PCs in order to fix the error, although that rarely helps. Still, we recommend you try it first.

There are several reasons why this error might occur. Third-party security software can block the update, or corrupted system files or Office itself can cause it. Other factors like connectivity issues, insufficient disk space, or incomplete installation of previous updates can also be the culprit.

Fix 5. Disable or uninstall third-party software

Third-party security software, VPNs, and firewalls can cause Office update errors because they can interfere with the update process. These security programs are designed to protect the user's system by monitoring and controlling network traffic, which can sometimes block legitimate applications and updates from running properly.

When a user tries to update Office, the update program tries to establish a connection with Microsoft's servers to download and install the latest updates. However, security software, VPNs, and firewalls can mistakenly identify this connection as a potential threat and block it.

Additionally, some security software may not be compatible with Office updates or may interfere with certain files or components required for the update to run correctly. This can cause Office update error 30015-26 to occur.

Protect your online privacy with a VPN client

A VPN is crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speeds. The best solution for your ultimate privacy is Private Internet Access – be anonymous and secure online.
