Preamble. Running Arcgis and Business Analyst 10.4 on a MacBook Pro with parallels, Windows10 VM with 8G dedicated, having just upgraded windows from windows7 and at the same time 10.3.1 to 10.4
I first try to use Business Analyst tools for a new study. Strange, all the menu options are greyed out, and when I try to run a tool BA reports that I have no license available. Well, I had one in 10.3.1. ArcGIS Administrator reports that I have a single use permanent license for BA desktop.
I open a chat session describing the problem. After 15mins it becomes clear that nobody from ESRI is going to be at the other end of the chat. Perhaps there was a glitch. I try again, and wait 22 minutes. Still nobody. I have now expended 90+mins with nothing done. I file a written bug report and try to do other work, without using BA.
