Add-PsSnapin WebAdministration in Windows7
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

6.) I try in ps1 file

Write-Host $succeeded
if (($succeeded -ne $null) -and ($succeeded.GetType() -eq [System.Exception]))
{
#Could not import, trying to snapin
add-pssnapin WebAdministration
}
$succeeded is null, and "add-pssnapin WebAdministration" produces error message: Add-PSSnapin : The Windows PowerShell snap-in 'WebAdministration' is not installed on this machine.
PS C:\Program Files\IIS> Add-PSSnapin WebAdministration
Add-PSSnapin : El complemento WebAdministration de Windows PowerShell no está instalado en este equipo

+ Add-PSSnapin <<<< WebAdministration
+ CategoryInfo : InvalidArgument: (WebAdministration:String) [Add-PSSnapin], PSArgum
+ FullyQualifiedErrorId : AddPSSnapInRead,Microsoft.PowerShell.Commands.AddPSSnapinCommand
any suggestions about it ? Why fails Add-PSSnapin WebAdministration ?
UPDATE: I'm confused when exactly do I use Add-PSSnapin and when do I use Import-Module
http://social.technet.microsoft.com/Forums/en/ITCG/thread/3e1ca6e1-d197-4c04-a145-1e922814a618
surely, WebAdministration is only Module, and has'nt PSSnapin. May be...

Answer
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
}
}
}
