When updating systems the agent isn't always showing up in the add/remove list. Some systems it does, others it does not. The ones that don't have it in the list can still launch the program and it shows the agent as being updated. This is the Summer v17.3.57 b2 release. This of course makes it difficult to find out which systems still need the updated agent. Not good! Over 50% of our computers appear to have this issue (about 750 PC's so far and counting).
