I recently upgrade (did clean install) of my laptop from Windows Vista Ultimate to Windows 7 Ultimate.  On the previous version (Vista) I was using Iconpackager 4.x and was able to change the .exe of a program icon so that my desktop always looked nice.  Since upgrading to Windows 7 and Iconpackager 5.x  (through Impulse) I cannot seem to change the icon that is shown for .exe- I see the 'Change Icon' option when I right-click on the program file, but it does not seem to work.  Any ideas? Anyone?

I am not trying to change the icons in the .exe file- just how a particular program icon is shown on my desktop.  Icon Packager version 4.1 and 4.2 seemed to work with no problems.... but Version 5 seems to have on effect.
