Please reference previous thread with same title, sans 2.
In July 2015, we had a set of laptops that we due a scheduled update with the latest Nav Def file. The laptops are in a controlled environment, no internet access. The had Windows XP and SEP 11.0.6000.550 . After the update was executed, the pop-up window read "Intelligent Updater session complete. All updates failed to install on the machine. For more details about the processing, please check the log file "Log.IntelligentUpdater.txt" created in the user's temporary directory.” Going to the SEP GUI, it was determined that the status was green, and all was good despite the pop-up window error message.
This caused a lot of panic about our systems being protected. We know about the EOSL for SEP and the risks of Windows XP, but that is just what we have to live with. In discussions on this website, it was said that the computers are still protected even though the pop up box says the update failed. Since then, we have made updates in October, 2015, Dec 2015, and several times in 2016, with no mention of the pop-up error message again. Is there any explanation for this? We have also updated to Windows 7 in December 2015.
