Missing SQLServer2016-SSEI-Expr.exe Package

[wh1t3-n01s3]

Following the Automagic install instructions, the SQLServer2016-SSEI-Expr.exe is not automatically downloaded into packages. It may be that it's not possible to script the download, but the instructions don't indicate that it needs to be manually downloaded prior to running script 3.

Tracked this issue down.
In the 1_Download-src.ps1 file SQLServer2016-SSEI-Expr.exe is sourced from an ad network redirect

$AppList += ,@('SQLServer2016-SSEI-Expr.exe', "$DownloadFolder\Sql", 'https://ib.adnxs.com/seg?add=1&redir=https%3A%2F%2Fgo.microsoft.com%2Ffwlink%2F%3FLinkID%3D799012')

For anyone else curious adnxs.com is an ad network. If you strip off the ad URL you get https://go.microsoft.com/fwlink/?linkid=799012/. Unfortunately, this URL is dead.

After doing some quick Google-Fu, I stumbled on this URL - https://www.microsoft.com/en-us/download/details.aspx?id=54284 which is exactly what we need.
