Changing the icon in a stanalone projector

Hi,

I have a standalone projector that is being burned to a hybrid Mac/PC CD. I need to change the icons for both the PC’s .exe file and also the Mac Projector file.

I don’t need any fullblown software editors, just something that can change the icons. Also, I’d rather not buy/download different pieces of software for each operating system.

Is there anything out there? So far the threads I’ve found haven’t been very precise or link to outdated files. Shareware/freeware would be ideal, but I can spend < $100 US as long as it covers both OS’s.

Please help…
