# Install-Package - the following commands are already available on this system

Corrigez l'erreur Install-Package indiquant que les commandes sont déjà disponibles sur ce système lors de l'installation du module Devolutions.PowerShell en supprimant les modules plus anciens.

Lors d'une tentative d'installation du nouveau module Devolutions.PowerShell, l'erreur suivante est générée :

```
Install-Package: The following commands are already available on this system:'Close-DSSession,Convert-PSCustomObjectToXML,Convert-XMLToPSCustomObject,Convert-XMLToSerializedString,Disable-DSHubSystemVaultPermission,Set-HubUser,Set-HubVault,Set-HubVaultPermission.' This module 'Devolutions.PowerShell' may override the existing commands. If you still want to install this module 'Devolutions.PowerShell', use -AllowClobber parameter.
```

### Solution 1

Désinstallez les modules précédents : RemoteDesktopManager, Devolutions.Server et Devolutions.Hub.

Voici les différentes commandes pour les désinstaller : `Uninstall-Module RemoteDesktopManager -AllVersions`

`Uninstall-Module Devolutions.Server -AllVersions`

`Uninstall-Module Devolutions.Hub -AllVersions`

### Solution 2

En exécutant l'applet de commande `Get-Module -ListAvailable`, si certains des modules sont toujours visibles dans la liste et que le type de module est Binary, ils doivent être supprimés manuellement dans le chemin indiqué.

## 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/fr/knowledge-base/troubleshooting-articles/install-package-the-following-commands-are-already-available-on-this-system.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.
