Symptoms
When trying to download Microsoft patches MS15-106 and above you receive the error message "Connection lost: The remote certificate is invalid according to the validation procedure."
Cause
Environmental settings are preventing the Baltimore Cyber Trust Root Certificate from downloading OR it is in your Untrusted Certificates store.
Resolution
If the Certificate is not in your "Computer account" Certificate store under "Trusted Root Certification Authority" it is either unable to download or it is in your "Untrusted Certificates" store. If you find the Baltimore Cyber Trust Root Certificate under the "Untrusted Certificates" store simply move it to the "Trusted Root Certification Authority" store by dragging and dropping it.
If the certificate is not in either certificate store you will need to download it manually and import it into the "Trusted Root Certification Authority" store. To do this, find the Microsoft Bulletin ID URL for the problem patch (This can be found in Patch View) and navigate to the site by clicking on the link.
Once you are there you will receive an error stating there is a problem with the sites security certificate. Download the Baltimore Cyber Trust certificate from the browser and import it into your "Computer Account" Trusted Root Certification Authority Store. You should now be able to navigate to the Microsoft Bulletin ID page without error as well as successfully download the patch in Shavlik Protect.
Additional Information
If you get to the Microsoft Bulletin ID URL and you receive no Certificate Error you most likely have the Certificate in your "Current User" Trusted Root store but not in your "Local Computer" Trusted Root store. To remedy this you will need to export your Baltimore Cyber Trust Cert and Import it into your Local Computer certificate store.
