I tried out the current iconpackager trial, and it totally messed up all of my icons. They're all wrong; my DVD icon looks like a floppy disk, my default icon is a big UAC shield, and so on. Restoring to windows default doesn't help, uninstalling iconpackager doesn't help, and running the odnt_zapper doesn't help.
Reading through the forums, it looks like my mistake was installing 4.2 on windows 7, and this is fixed with version 5.0-- but I can't get version 5.0 without paying, which obviously I'm not particularly inclined to do at this exact point in my life. Can anyone help with this? Am I basically out of luck?
