Powershell 2.0 Download File «90% AUTHENTIC»

bitsadmin /transfer "MyDownloadJob" /download /priority normal $url $output

GitHub often returns a redirect. WebClient does not auto-follow redirects in all cases. Use this workaround: powershell 2.0 download file

$webClient = New-Object System.Net.WebClient
$webClient.Headers.Add("Accept", "application/octet-stream")
# GitHub raw content workaround
$webClient.Headers.Add("User-Agent", "PowerShell/2.0")

$webClient.Headers.Add("User-Agent", "PowerShell/2.0 Script") $webClient

Fix: Provide explicit credentials:

$webClient.Credentials = New-Object System.Net.NetworkCredential("username", "password")
# Or for domain auth:
$webClient.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
