Hello. My name is Michael. I can help you with your question.
It sounds like you may have an installation that partially installed and then failed.
If this is a Windows computer, please go to the control panel, then to programs, and uninstall a program. Look in there to see if you see a previous install. If you do, please right click and uninstall from there. If not, let me know and we can look at a way to remove it manually.
