[Command Centre - Errors](/knowledge-hub/products/cc-software/troubleshoot/command-centre-errors.md) › The Service did not respond to the start or control request in a timely fashion

**Error:** "The service did not respond to the start or control request in a timely fashion."

The message appears when trying to start the **Controller service** on a new install, after it failed to start during the install.

![Error: the service did not respond to the start or control request in a timely fashion](https://328339335-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F6bM8WhlBE9BYizPWJaPN%2Fuploads%2Fgit-blob-674bcdbd3309bbb63c4f8e42f4cbf7e4678e3c6c%2FSECHUB-CCS-ERR-SERVICE-TIMEOUT-01.png?alt=media)

In the Windows Event Viewer under **Application**, the Controller service fails to start because it is looking for **.NET Core 8.0.8**, which is supported only after **Windows 10 22H2**.

## Resolution

Upgrade the Windows 10 installation to at least **22H2**, then reinstall Command Centre over the top.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.security.gallagher.com/knowledge-hub/products/cc-software/troubleshoot/command-centre-errors/command-centre-errors-the-service-did.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
