# Troubleshooting

> Resolve capability activation, update, and advanced diagnostic issues.

Use this chapter when a capability cannot start, an update does not complete, or you need to prepare useful information for support. For everyday “how do I use this?” questions, read [Frequently asked questions](/en/help/faq).

## Capability activation failed

Enable Word and LaTeX from **Settings → Capability management**. The status label describes the next step:

* **Needs upgrade / Upgrade recommended:** update Office to Word 2022 or later, or Microsoft 365, and retry.
* **Unable to confirm:** Otterflow could not determine the environment and did **not** change Office add-in configuration. Retry the check later.
* **Needs attention:** follow the specific instructions displayed on the capability card.

Disabling and enabling a capability runs the check again, so reactivation can take longer. See [Capability management](/en/settings/capability-management) for the complete status reference.

## Check for updates

Many issues are fixed in newer versions. Open **Settings → About** and use the update control to check, download, and install the latest version.

## Export useful diagnostic information

When contacting support, include:

* the application version from **Settings → About**;
* exact reproduction steps, expected result, and actual result; and
* the affected feature and visible error message.

Specific information makes a problem easier to reproduce and resolve.

## Contact us

Use the official website or community links in **Settings → About** to ask for help or submit feedback.

## Advanced: Extensions (MCP)

> **For advanced users and developers only.** Most users do not need this area.

The **Extensions** page is hidden by default. It appears only after Developer mode is enabled in **Settings → About**. It exposes low-level diagnostic capabilities such as Office MCP runtime status, connection diagnosis, and health-log export. Do not manually intervene in these services during normal use; Word and LaTeX activation should be handled from [Capability management](/en/settings/capability-management).
