PSWindowsUpdate File Not Found Exception

Question

I recently updated PSWindowsUpdate from version 1.6.1.1 to the latest version (2.1.0.1) and when I try to run the script:

Write-Host "      Centralized Update"
Write-Host "================================"

ipmo activedirectory
$computers = Get-ADComputer -Filter {enabled -eq $true} -properties * -SearchBase "OU=Workstations, DC=contoso, DC=com" | select name
$Script = {ipmo PSWindowsUpdate; Get-WUInstall -AcceptAll -Install -Verbose}

foreach ($computer in $computers) {
    Write-Host "Running update on:" $computer.name
    Invoke-WUJob -ComputerName $computer.name -Script $Script -Confirm:$false -RunNow
}

Write-Host "================================"
pause

I get the following error:

Invoke-WUJob : The system cannot find the file specified. (Exception from HRESULT: 0x80070002)
At C:\Users\Administrator\Desktop\Update_Workstations.ps1:10
char:2
+     Invoke-WUJob -ComputerName $computer.name -Script $Script -Confir ...
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Invoke-WUJob], FileNotFoundException
    + FullyQualifiedErrorId : System.IO.FileNotFoundException,PSWindowsUpdate.InvokeWUJob

The only edit to the script was to change:

Invoke-WUInstall -ComputerName $computer.name -Script $Script -Confirm:$false

To:

Invoke-WUJob -ComputerName $computer.name -Script $Script -Confirm:$false -RunNow

More details:

The version of PowerShell is 5.1 (both client and server side)
The list of terminals is correctly extracted from the "Workstations" organizational unit
I can connect via "enter-pssession" to all the terminals without problems
Using "Invoke-Command" instead of "Invoke-WUJob" run but fails at the time of download with the error "UnauthorizedAccessException"

What's wrong with the code ? before updating to version 2.1.0.1 it works fine

Did you verify, that PSWindowsUpdate is loaded, if you run the script? (you might want to add Import-Module -Name PSWindowsUpdate. Also, can you test if Invoke-WUJob -ComputerName aComputerName -Confirm:$false -RunNow without anything else runs in an interactive shell? — vrdse

The problem seems to be the "Invoke-WUJob" command, it has the same error both from a script and directly from the console. However, the PSWindowsUpdate module is loaded correctly, using: Invoke-Command -ComputerName $computer.name -Script {ipmo pswindowsupdate ; get-module pswindowsupdate} it shows the correct version (2.1.0.1). — Danfossi

I was running into Invoke-WUJob : The request is not supported. (Exception from HRESULT: 0x80070032) and this answer finally resolved it for me!

I was getting the error : [Invoke-WUJob : The network path was not found. (Exception from HRESULT: 0x80070035)] and the command above saved my sanity.
