Error 1260 or Access Denied Error when installing or updating BLS-2018

As a note: Windows 2003 and Windows XP are not officially supported by BLS-2018. We strongly encourage you to network a computer with Windows 7 or newer to your scoring system and move BLS to that computer.
When trying to install program, the installation fails when installing giving an Access Denied error.  The error may appear such as this:
Error 1260: Windows cannot open this program because it has been prevented by a software restriction policy. For more information, open Event Viewer or contact your system administrator.
This issue can be caused by a couple of reasons:
  1. This could be caused by Microsoft's update release KB2918614 and/or KB3072630.
  2. This could be related to changes in requirements by Microsoft for companies to use stronger SHA-2 digital signatures to prove that an installer or EXE came from the software developer instead of the weaker SHA-1 digital signature.  Windows XP and Windows 2003 were not updated to support the stronger SHA-2 digital signatures and may cause an install or update process to not complete when validating the digital signature.
If you do receive this error, use the steps below to correct the problem. If you have not yet installed this update, go to "Hide Update" section below to hide the update so that you don’t install it at a later date.
