Do you mean, when we push the packages does the pkg file get stuck? We set it up so that we released it to specific areas and then it came up with a pop up asking them if they want to download or install later. I can't make any distinction right now that if they choose download or later, if it affects this particular issue or not. All I happen to know is that there is a pkg file that sits in the download folder and I have to stop symantec and remove the file and start smc again to get it to work.
In the particular users case it wasn't updating her client. Even after she clicked download, just didn't seem to ever want to update her client.
