install Windows 10 language packs and associated features on demand

Question

I'm try to install Windows 10 using TS with multiple language packs but its not working.

My TS
Download language packs into an Temp folder (I can see this folder being created and all of the files being download e.g. LP, FOD)
Then I run powershell script to install LP

Param ($contentPath)  
  
Set-StrictMode -Off  
  
$logFile = "C:\Language\InstallLanguagePacks.log"  
if(!(Test-Path $logFile)){New-Item -Path $logFile -Force}  
  
$contentPath | Tee-Object -FilePath $logFile -Append  
  
[array]$AllLPs = Get-ChildItem "$contentPath\*\LP\Microsoft-Windows-Client-Language-Pack_x64*.cab"  
"{0:u} | Found {1} language packs:" -f [datetime]::Now, $AllLPs.Count | Tee-Object -FilePath $logFile -Append  
$AllLPs.FullName | Tee-Object -FilePath $logFile -Append  
  
Foreach ($lp in $AllLPs)  
{  
    "Install new LP $lp" | Tee-Object -FilePath $logFile -Append  
    $LPPath=$lp.FullName  
    Add-WindowsPackage -Online -PackagePath $("$LPPath") -NoRestart -Verbose 3>&1 4>&1 |   
    ForEach-Object {"{0:u} | {1}" -f [DateTime]::Now, ($_ | Out-String) | Tee-Object -FilePath $logFile -Append }  
}  

Then i Run the Fod script to install all of the Fods.

Param ($contentPath)  
  
Set-StrictMode -Off  
  
$logFile = "C:\Language\InstallLanguagePacks-FOD.log"  
if(!(Test-Path $logFile)){New-Item -Path $logFile -Force}  
  
Start-Sleep -Seconds 2  
$installedLP = Get-WindowsPackage -Online -PackageName "*Client-languagePack*" |  
    Where-Object {$_.PackageState -eq 'Installed' -and $_.PackageName -notmatch '~en-US~'}  
  
"{0:u} | Detected installed Language packs:" -f [datetime]::Now | Tee-Object -FilePath $logFile -Append  
($installedLP | Select-Object CapacityID, PackageName | Out-String -Stream) | Tee-Object -FilePath $logFile -Append  
  
$FODCat = @('Microsoft-Windows-LanguageFeatures-Basic-',  
            'Microsoft-Windows-LanguageFeatures-Fonts-',  
            'Microsoft-Windows-LanguageFeatures-OCR-',  
            'Microsoft-Windows-LanguageFeatures-Handwriting-',  
            'Microsoft-Windows-LanguageFeatures-TextToSpeech-',  
            'Microsoft-Windows-LanguageFeatures-Speech-',  
            'Microsoft-Windows-InternationalFeatures-'  
            )  
$FODs =@()  
  
foreach($Item in $FODCat)  
{  
    $FODs += Get-ChildItem "$contentPath\*\FOD\$Item*.cab" | Select-Object -ExpandProperty FullName  
}  
  
"{0:} | Reading FOd content source. Found {1} language and readion feature on demand (FOD): " -f [datetime]::Now, $FODs.Count |   
    Tee-Object -FilePath $logFile -Append  
  
If($FODs.Count) {   
    "",$FODs.Substring($contentPath.Length),"" | Tee-Object -FilePath $logFile -Append  
    $FODs | Tee-Object -FilePath $logFile -Append   
}  
  
foreach ($fp in $FODs)  
{  
    "Installing FoD $fp" | Tee-Object -FilePath $logFile -Append  
     Add-WindowsPackage -Online -PackagePath "$($fp)" -NoRestart -PreventPending -Verbose 3>&1 4>&1 |   
    ForEach-Object {"{0:u} | {1}" -f [DateTime]::Now, ($_ | Out-String) | Tee-Object -FilePath $logFile -Append }  
}  

but nothing happens, I try to install LP manually in winpe mode but I get following error

Hi,

We use the command of Add-WindowsPackage -Online, which is for the running OS, so it is suggested to install LP in full OS, and then check if it is working.

Besides, we could refer to this link to install language pack with integrating MDT with ConfigMgr.
