What was error message when using Update 3?
There was no error; all seamed to install as smoothly as previous updates.
I suspect that components of Update 3 has not been installed properly. You have to uninstall Update 2 first, then install Update 3. Over-installing product is not allowed.
When launching the install of Update 3 it mentions that it will first uninstall Update 2. I hoped this was working.
I realize it might be impossible to uninstall Update 3 now, since you installed the Update 3 unsuccessfully but it exists in your system. Please ask help to IT (or you do it carefully) to remove product info in your system, then you can install Update 3 directly.
It was reverting back to Update 2 that failed. I solved it by reinstalling Update 3, because then uninstall of Update 3 was possible.As you suggested:
Itis good that you can collect data from command line, and displayedon GUI. I don't knowif it was an integration issue.Anyway it works.
I have concern on your Bad news -can this problem be repeated without using lightweight-hotspots?
