How do I import a module for script use?

Question

I have a script that uses the AD module for some operations. Here is the code:
#04/24/2014
#UsAer Logger
#Author: Alexander Bazzi
#Property of AerSale, Inc
Import-Module ActiveDirectory
$username=$env:username
$computerName=$env:computername
$userProperties = Get-ADUser $username
$departmentOU = ($userProperties.DistinguishedName -split ',OU=')[1]
$officeOU=($userProperties.DistinguishedName -split ',OU=')[2]
$pathOutUser = "C:\Scripts\UsAer_Logger\Output\$officeOU\$departmentOU.txt"
if(Test-Path $pathOutUser)
$computerName >> $pathOutUser
else {
New-Item $pathOutUser
$computerName >> $pathOutUser
When I try to run it on PowerShell ISE, I get the following exception: 
Import-Module : The following error occurred while loading the extended type da
ta file: 
Microsoft.PowerShell, C:\Windows\system32\WindowsPowerShell\v1.0\Modules\Active
Directory\ActiveDirectory.Types.ps1xml : File skipped because it was already pr
esent from "Microsoft.PowerShell".
Microsoft.PowerShell, C:\Windows\system32\WindowsPowerShell\v1.0\Modules\Active
Directory\ActiveDirectory.Types.ps1xml : File skipped because it was already pr

Directory\ActiveDirectory.Types.ps1xml : File skipped because it was already pr
esent from "Microsoft.PowerShell".
I tried running it without the Import-Module cmdlt, but it didn't recognize the Get-ADUser command. If you could shed some light on this, I'd really appreciate it!
Many thanks in advance.
Best,
Alex

Answer 1

You have two different copies of Active Directory module installed.
Get-Module -list Act*
See if there is a second version.  It is also possible that you are loading something in your profile that is loading those components.  Try start PowerShell with the -NoProfile switch then import AD.  If that works then inspect your profiles
- all of them.,
¯\_(ツ)_/¯
