# Errore di certificato non valido durante l'aggiornamento di Remote Desktop Manager

Remote Desktop Manager mostra un messaggio di errore "Invalid certificate" quando si tenta di eseguire l'aggiornamento da una versione precedente alla 2023.2.34.

Come precauzione di sicurezza, Remote Desktop Manager include un elenco di certificati accettati per garantire che gli aggiornamenti siano distribuiti da Devolutions (un metodo chiamato certificate pinning).

### Soluzione

Per risolvere questo problema, scarichi e installi manualmente l'aggiornamento tramite il suo browser.

1. Nella barra multifunzione di Remote Desktop Manager, vada su ***Help – Check for updates***.
2. Nella scheda ***Update available*** che si apre, clicchi su ***Download***, poi su ***Download update using your default browser***. Il suo browser si apre e il download dovrebbe iniziare.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/rdm/it/knowledge-base/troubleshooting-articles/invalid-certificate-error-when-updating-remote-desktop-manager.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
