After installing Spark and going through the initial email address verification, the Spark app imply won't launch. Nothing happens whatsoever when clicking the launcher. I called Cisco support but that wasn't helpful. Apparently the executable modifies a text file called sparklauncher.txt. Inside it there is a line "Spark executable beside launcher is backlisted". Support indicated that communication to the head end is blocked so the rest of the software isn't installed? They sent me a Network Requirements doc Network Requirements for Cisco Spark Services (... | Cisco Cloud Collaboration Help Central. But in checking that, there is nothing preventing communication outside. It seems to be a design flaw in Spark that there isn't more useful info upon failure to load. Any thoughts?
