InstallShield file overwrite not working

I have an application that is installed using Install Shield 2012 (SP1). I need to install a new version of the app so I built another setup using the previous one as a starting point and then I simply changed the version number. The only file that changed is the app exe. When I run the new setup it recognizes that it is an upgrade and runs through normally but my old exe file does not get overwritten by the new version exe. The old exe version shows as 4.6 and the new one is 5.2. I have tried setting the always overwrite option on the new exe component file but it still does not overwrite. Any suggestions?

Detailed installation log will tell. http://support.microsoft.com/KB/223300 . Look in the log, or post it here for us to look at.

I think I may see what the issue is. The exe in question has a space in the file name and in the log the space is being replaced with an underscore. This causes the install value to show as absent. I will rename the exe and remove the space and see if that fixes the problem.

That seemed to do it. Thanks for pointing me to the log.
