SSL chain issues with Chrome

[reverent]

We recently moved from using IE to Chrome and as you know, the new version of Chrome 58 require a SAN in the https certificate. I regenerated the certificate with the appropriate SAN and the issue I am now running into is with IIS express, I do not know how to include the certificate chain.

On all of our other web servers running Apache, I just edit the conf files in sites-available and add

SSLCertificateChainFile /etc/apache2/ssl/chain.p7b

and it works, but IIS Express is another beast that I can't quite figure out.

I have https working with Lansweeper, so I have followed the instructions, but I want to get rid of the "not secure" designation by Chrome 58 because it doesn't recognize the intermediary certificates. I use an internal CA running Windows Server 2012 so I control both sides of the equation, and I can download the certificate chain file, but I just don't know how to get Lansweeper (IIS Express) to reference it.
