You can use ResHacker but not for changing projectors icon instead you have to change projec32.skl.
Changing icon according to macromedia TechNote 32-bit projector (Director 5.0 and above) The process is similar to a 16-bit projector, but you need to make a copy of and edit PROJEC32.skl, and there are two icons in the APPICON resource, a 32x32-pixel icon and a smaller16x16. 1 Make a backup copy of projec32.skl. 2 Open projec32.skl as a .exe file format in your favorite resource editor (for example Microangelo). 3 Edit both the 16x16 and 32x32 icon resources in the icon resource called APPICON. The resource editor may have a pull-down menu to select the different sizes. 4 Save the file. Make sure it is still called projec32.skl and is in the same directory. 5 Create a 32-bit projector. It will now have your own icon. 6 Optional: restore the original version of projec32.skl. Modifying a 32-bit projector icon requires a 32-bit resource editor, because I6-bit code and 32-bit code use totally different file formats. For example, the 16-bit AppStudio in Microsoft Visual C 1.X cannot edit the 32-bit Projec32.skl. Attempts to do so result in the error: "Incompatible magic number in executable". Additionally, when using the MSVC 4.0 DevStudio, this process can only be performed while running Windows NT. Microsoft states that this occurs because the API to modify a resource inside 32-bit code is only supported in Windows NT, not Windows 95. See the MSVC 4.0 FAQ in the Microsoft Visual C KnowledgeBase (Q138735), and another Microsoft KB article Q139030. There are dedicated resource-hacking utilities that don't use an API but just force an icon into the code. Some of these will find and replace the 32x32 large icon in code, but not the 16x16 small icon. Microangelo is a shareware utility that edits icons and also edits cursors and animated cursors. Another icon editor is IconMover from Integrated Graphics (available at www.shareware.com and elsewhere). To check the 32x32 icon in the resulting application, select the file on the desktop or Explorer and choose File-Properties. To check the 16x16 icon, change the folder in which the application resides to View-Small icons. It may be necessary to refresh the view to force Windows to display the changed icon. The Custom Icon does not show up everywhere See Why can't I change a projector's title bar, task bar and task list icons? (TechNote 1107).
