I've updated my version of PhpED to the latest (17). I noticed that I still have prior versions occupying space under the C:\Program Files\NuSphere folder. For example, I have "PhpED", "PhpED 16", and "PhpED 17" sub-folders. I'm assuming that's because I decided to install newer versions into their own folder in case I needed to revert back. So, how does one go about cleanly removing a prior version without damaging the current version? I looked in Control Panel and saw that it only has one version listed - probably the latest. Is it as simple as removing the sub-folders?

run unins000.exe in them one by one starting with the oldest version toward the newest. Then install the latest one more time into the same directory where it has already been installed.
