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

Fix the Install-Package commands already available on this system error when installing the Devolutions.PowerShell module by removing older modules.

When trying to install the new Devolutions.PowerShell module, the following error is raised:

```
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

Uninstall the previous modules: RemoteDesktopManager, Devolutions.Server, and Devolutions.Hub.

Here are the different commands to uninstall them: `Uninstall-Module RemoteDesktopManager -AllVersions`

`Uninstall-Module Devolutions.Server -AllVersions`

`Uninstall-Module Devolutions.Hub -AllVersions`

### Solution 2

Running the `Get-Module -ListAvailable` cmdlet, if some of the modules are still visible in the list and the module type is Binary, then they need to be manually removed in the given path.

## 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/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.
