I received an update notice - WebSite X5 - v13.1.0.5. I installed prior updates w/no issues. This one does not install and brings me to the last pop up box with a triangle in it as you can see in screen shot 4.  I tried everything possible from restarting program, reboot pc and disabled Norton Security AntiVirus, which I will try again.  This has nothing to do with any published website URL and has to do with the main program start up screen/window with a new update message that just won't install. I checked through all of the help messages as recommended and didn't find anything related to my problem.  I HOPE THERE IS A SOLUTION FOR THIS PROBLEM THAT I AM HAVING TO INSTALL THE UPDATE...

THANK YOU, Joe Garofalo, ***
