Add-PsSnapin WebAdministration in Windows7

Question

I want to use PowerShell to administer my IIS7 on Windows7 64 bits. I try install IIS7 Powershell snap-in http://www.iis.net/download/PowerShell I "Run as administrator", then typing the command listed below: msiexec /I iis7psprov_x64.msi but I get this error message: "The PowerShell snap-in is part of Windows Operating System. Please install via Programs and Features or Server Manager" I think this particular feature is not necessary to load the WebAdministration module but I active all options in "Programs and features | turn Windows features on or off | IIS | Web Management Tools | IIS Management Scripts and Tools I do those checks: 1.) Power-Shell is installed ``` PS C:\Program Files\IIS> $Host.Version Major Minor Build Revision ----- ----- ----- -------- 2 0 -1 -1 PS C:\Program Files\IIS> $PSVersionTable Name Value ---- ----- CLRVersion 2.0.50727.5448 BuildVersion 6.1.7601.17514 PSVersion 2.0 WSManStackVersion 2.0 PSCompatibleVersions {1.0, 2.0} SerializationVersion 1.1.0.1 PSRem…

Here is the function I have in my profile.ps1 for loading the WebAdmin module. It covers IIS 7 and 7.5

```
# Web administration is loaded as a module on Windows 2008 R2 but as a set of snapins
# for Windows 2008 (not R2)

function Util-Load-Web-Administration
{
    $ModuleName = "WebAdministration"
    $ModuleLoaded = $false
    $LoadAsSnapin = $false

if ($PSVersionTable.PSVersion.Major -ge 2)
    {
        if ((Get-Module -ListAvailable | ForEach-Object {$_.Name}) -contains $ModuleName)
        {
            Import-Module $ModuleName

if ((Get-Module | ForEach-Object {$_.Name}) -contains $ModuleName)
                { $ModuleLoaded = $true } else { $LoadAsSnapin = $true }
        }
        elseif ((Get-Module | ForEach-Object {$_.Name}) -contains $ModuleName)
            { $ModuleLoaded = $true } else { $LoadAsSnapin = $true }
    }
    else
    { $LoadAsSnapin = $true }

if ($LoadAsSnapin)
    {
        try
        {
            if ((Get-PSSnapin -Registered | ForEach-Object {$_.Name}) -contains $ModuleName)
            {
                if ((Get-PSSnapin -Name $ModuleName -ErrorAction SilentlyContinue) -eq $null) 
                    { Add-PSSnapin $ModuleName }

if ((Get-PSSnapin | ForEach-Object {$_.Name}) -contains $ModuleName)
                    { $ModuleLoaded = $true }
            }
            elseif ((Get-PSSnapin | ForEach-Object {$_.Name}) -contains $ModuleName)
                { $ModuleLoaded = $true }
        }

catch
        {
            Write-Error "`t`t$($MyInvocation.InvocationName): $_"
            Exit
        }
    }
}
```
