Could not load file or assembly 'Microsoft.Web.Administration, Version=

Hi all,

I have a win server 2016 1607 Build OS 14393.14 with IIS 10.0.14
I try to run some PowerShell scripts to configure websites.
Some of those code is as below

            Start-Sleep -s 10  
            $site = Get-IISSite $siteName  

While it executes, below error occurs

Get-IISSite : Could not load file or assembly 'Microsoft.Web.Administration, Version=, Culture=neutral,  
PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.  

Start-IISCommitDelay : The type initializer for 'Microsoft.IIS.Powershell.Commands.MWAMgr' threw an exception.  
At C:\Program Files (x86)\........MainScript.ps1:228 char:13  

I have tried to copy Microsoft.Web.Management and Microsoft.Web.Administration dll file from some other (win 10 LTSC) to overwrite and test is it working. Failed to overwrite since access protected, though the use has admin privileges.

This same script works on win 10 and win 2019

Thank you for your consideration and help.

    Do you find that file in the directory "C:\Windows\System32\inetsrv"? If you do, does its version match the version in the error message?

    Check the "Turn Windows features on or off" and verify that you have version 7 of the IIS Management Console installed.

    In your script you specify a specific version of the DLL must be loaded. I believe that is the version delivered with IIS7. If you have IIS6 installed the DLL won't be loaded.
