Installing PowerShellGet on Windows


Windows PowerShell 5.1 comes with version of PowerShellGet preinstalled. This version of PowerShellGet has a limited features and doesn't support the updated capabilities of the PowerShell Gallery. To be supported, you must update to the latest version.

PowerShell 6.0 shipped with version 1.6.0 of PowerShellGet. PowerShell 7.0 shipped with version 2.2.3 of PowerShellGet. The current supported version of PowerShellGet is 2.2.5. If you are running Windows PowerShell 5.1, you must install a newer version.

For best results, you should always install the latest supported version.

Updating the preinstalled version of PowerShellGet

The PowerShellGet module includes cmdlets to install and update modules:

  • Install-Module installs the latest (non-prerelease) version of a module.
  • Update-Module installs the latest (non-prerelease) version of a module if it is newer than the currently installed module. However, this cmdlet only works if the previous version was installed using Install-Module.

To update the preinstalled module you must use Install-Module. After you have installed the new version from the PowerShell Gallery, you can use Update-Module to install newer releases.

Updating PowerShellGet for Windows PowerShell 5.1

System requirements

  • PowerShellGet requires .NET Framework 4.5 or above. For more information, see Install the .NET Framework for developers.

  • To access the PowerShell Gallery, you must use Transport Layer Security (TLS) 1.2 or higher. By default, PowerShell is not configured to use TLS 1.2. Use the following command to enable TLS 1.2 in your PowerShell session.

    [Net.ServicePointManager]::SecurityProtocol = [Net.ServicePointManager]::SecurityProtocol -bor [Net.SecurityProtocolType]::Tls12

    We also recommend adding this line of code to your PowerShell profile script. For more information about profiles, see about_Profiles.

Installing the latest version of PowerShellGet

Windows PowerShell 5.1 comes with PowerShellGet version, which doesn't include the NuGet provider. The provider is required by PowerShellGet when working with the PowerShell Gallery.


The following commands must be run from an elevated PowerShell session. Right-click the PowerShell icon and choose Run as administrator to start an elevated session.

There are two ways to install the NuGet provider:

  • Use Install-PackageProvider to install NuGet before installing other modules

    Run the following command to install the NuGet provider.

    Install-PackageProvider -Name NuGet -Force

    After you have installed the provider you should be able to use any of the PowerShellGet cmdlets with the PowerShell Gallery.

  • Let Install-Module prompt you to install the NuGet provider

    The following command attempts to install the updated PowerShellGet module without the NuGet provider.

    Install-Module PowerShellGet -AllowClobber -Force

    Install-Module prompts you to install the NuGet provider. Type Y to install the provider.

    NuGet provider is required to continue
    PowerShellGet requires NuGet provider version '' or newer to interact with NuGet-based
    repositories. The NuGet provider must be available in 'C:\Program Files\PackageManagement\ProviderAssemblies'
    or 'C:\Users\user1\AppData\Local\PackageManagement\ProviderAssemblies'. You can also install the NuGet
    provider by running 'Install-PackageProvider -Name NuGet -MinimumVersion -Force'. Do you
    want PowerShellGet to install and import the NuGet provider now?
    [Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"): Y
    VERBOSE: Installing NuGet provider.


If you have not configured TLS 1.2, any attempts to install the NuGet provider and other packages will fail.

After installing PowerShellGet

After you have installed the new version of PowerShellGet, you should open a new PowerShell session. PowerShell automatically loads the newest version of the module when you use a PowerShellGet cmdlet.

We also recommend that you register the PowerShell Gallery as a trusted repository. Use the following command:

Set-PSRepository -Name PSGallery -InstallationPolicy Trusted

For more information, see Set-PSRepository.
