I use admin command line, try to run setup.ps1, and get errors of SSL access:

I think it should do some setting for SSL connection, can not directly use System.Net.WebClient。
it should added something between those line in setup.ps1.

$wc = New-Object System.Net.WebClient
...
$wc.DownloadFile($url, "$CS/$LJ")
