So far, I've installed ithe latest client on 3 machines. The SEPm server and 2 - windows 10 1607 LTSB VDI machines (horizon). The server was fine but both clients reported warnings after the reboot.
"Download Insight is malfunctioning. File System Auto-Protect is malfunctioning
Details: Download insight is not functioning correctly due to the file system autoprotect status.
File System auto protect is not functioning correctly. Your protection definitions may be damaged or your product installation may be corrupt. "
For client 1, i rebooted a 2nd time and it has been green for the last 2 hours. For client 2, i didnt want to do a 2nd reboot and I was told by the Symantec tech that it is trying download files from the internet so just leave it and it will fix itself. It has been 2 hours and still shows the warning.
