When an upgrade is available you present a dialog box asking for permission to update. Your program provides a button to download for multiple installs but that button is shown at the same instant the download has started. Please consider changing your update dialog box to have "Download" and "Install" in addition to the exiting "Skip" and "Remind me later" that could save some bandwidth. As it is right now, clicking on "update" starts the download automatically and one has to go and find where that update is hidden in order to use it for other installs.
