In the RCP forum , LuoBin has run into a common problem when branding RCP applications - getting the darned icons to work! Windows XP is especially picky about its icons, and the PDE Product Editor that stuffs your icons into the native launcher program can fail quietly, leaving you scratching your head as to why the default icon is used.

Daniel Krügler pointed out a very nice resource for creating icons on Windows XP , and also recommends a tool called IconoMaker. I haven't used that one but the last time I had to do this I got good results from Microangelo. Providing a load of .bmp files may be good for a first pass, but for best results I think you're better off finding a good tool and creating a .ico file. See below for links and alternatives.

Questions for discussion:
What experiences have folks had getting icons to work, on Windows and other systems? Is there anything that PDE could do to make this easier? What kind of issues are we going to run into on Windows Vista? Post any bug numbers you've opened so we can vote on them.
