I presently have Open Office installed on one of my PCs. I would like to uninstall it so I can download the source code, compile it, and study the C++ code in it.
My concern is that I have had problems uninstalling drivers, programs, etc and reinstalling them before. It seems like the original installation may leave garbage in the registry, various folders, etc that mess up with the reinstall. For example, I think I never reinstalled a Oracle database, I always wiped the disk clean and reinstalled the op system first.
I can't wipe this disk, I have important data on it. Has anyone else uninstalled Open Office and then reinstalled it safely?

Thanks
