If you downloaded it, it either came as a zipped folder which you would need to expand to get to the installation icon or if it is on a CD it will probably just be in the root directory (or there may be an installation folder of some sort containing these files) and called setup.exe or install.exe or something like that. It's been so long since I installed it myself, I honestly can't remember precisely where it is but it shouldn't be too hard to find. Post back how you have the program (CD or download) if you still can't figure it out and I'll try to find my old Office 2003 disks (wherever they are -
) and see if I can locate the file and post it here. If you have a download, I'm afraid I don't know. Is the download a zip file or an exe file. If an exe file, that's the icon you're seeking. If a zip, unzip it and in the folder should be the icon you're looking for.
I hope this helps.
