The problem happens quite early, when the installation wrapper asks for a location to unzip the file. If the error happens, nothing is displayed. If the wrapper error doesn't happen. a Messagebox "WebPACK" : To begin the installation... is displayed.
Are you talking about the dialog in the attached screenshot? I have no trouble getting past that screen. InstallShield's wizard starts running for me, and starts copying files.
Perhaps the problem is due to a missing registry key or directory? If you'd like I can send you a relay trace to compare.
