# Errore di eccezione di violazione di accesso nelle sessioni RDP

Risolva l'errore System.AccessViolationException nelle sessioni RDP disabilitando l'API hooking nelle impostazioni di Remote Desktop Manager.

Quando si tenta di aprire una voce di sessione RDP, potrebbe comparire il messaggio di errore "An unexpected error has occurred. Please check the application logs for more information." Controllando i log dell'applicazione, viene visualizzato il seguente errore: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

### Soluzione

Disabiliti l'API hooking RDP nelle impostazioni di Remote Desktop Manager:

1. Vada su ***File – Impostazioni – Tipi – Desktop remoto – API Hooking***.
2. Nell'elenco a discesa ***Abilita API hooking***, selezioni ***Disabilitato***.
3. Riavvii Remote Desktop Manager per applicare le modifiche.

## 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://docs.devolutions.net/rdm/it/knowledge-base/troubleshooting-articles/access-violation-exception-error-in-rdp-sessions.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.
