I tried to use Install-ChocolateyPackage for installing msi file from an internal http server with NTLM auth , but got an error "(401) Unauthorized"..

After I updated

• Get-WebHeaders.ps1
• Get-WebFile.ps1

to use default credentials like this:

  $req = [System.Net.HttpWebRequest]::Create($url);
  $req.Credentials = [System.Net.CredentialCache]::DefaultCredentials

  $webclient = new-object System.Net.WebClient
  $webclient.Credentials = [System.Net.CredentialCache]::DefaultCredentials

Clarification - I did not mean default proxy - proxy is bypassed in my case according to IE settings - just use credentials for the site.
