title: Installshield Suite Update URL prompt
body: <p>Currently when i enter the Update URL and that is triggered by the Setup.exe application, the user has no choice but to download the update. There is no prompt to the user as IF they would like to perform the update first or not, they are simply forced to download the update when one is found. My exe is 430MB so i don't want them to be forced to download that if they don't want to. Is there a way to intercept the check and ONLY download/update the exe if the user answers YES to a prompt? I see in the /debuglog file that the URL is checked than immediately starts the download and displays the 'ISDownloadProgress' dialog. But also shows that the 'InstallationWelcome' dialog is shown as well even though it is not. It must be hidden somehow i guess.</p>
