# Force TLS 1.2 [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12 The second argument of DownloadFile must be a full file path (including the filename), not just a folder path. If you provide C:\Users\Name\Downloads\ , it will throw an exception. It must be C:\Users\Name\Downloads\file.ext . M Antarvasanacom: Top

# 4. Register the Event Handler for Completion # This block runs when the download finishes Register-ObjectEvent -InputObject $webClient -EventName DownloadFileCompleted -SourceIdentifier WebClient.DownloadFileCompleted -Action { Write-Host "Download Complete!" -ForegroundColor Green # Unregister events to clean up Unregister-Event -SourceIdentifier WebClient.DownloadProgressChanged Unregister-Event -SourceIdentifier WebClient.DownloadFileCompleted }
# Note: Because this is Async, the script continues running immediately. # If you want the script to wait until the download is done, you can add a loop: while ($webClient.IsBusy) { Start-Sleep -Milliseconds 100 } 1. SSL/TLS Errors PowerShell 2.0 (and the underlying .NET Framework) defaults to older security protocols (SSL3 or TLS 1.0). Most modern websites (like GitHub or AWS S3) require TLS 1.2 . If you get an error saying "The underlying connection was closed," run this command first:
Here is a complete script that downloads a file and shows a progress bar in the PowerShell console:
# Download the file $webClient.DownloadFile($url, $output) One of the main drawbacks of the basic method above is that it provides no visual feedback; the script simply pauses until the download finishes.
To implement a feature in PowerShell 2.0, you need to register an event handler for the DownloadProgressChanged event and use DownloadFileAsync .
