Turbotax 2016 did not uninstall properly and now I cannot reinstall from my CD. All online tips have failed. What can I do?

When attempting to open TurboTax 2016, a message said a file couldn't be found, that I should reinstall.  I tried, but message indicated I needed to reinstall first.  I used ReInstaller Pro to do so.  Nevertheless, when I try to reinstall from the CD, it continues to indicate that I need to remove the previous version.  I tried all of the tips I could find online, including the "flush" mode to reinstall, but nothing works.  Do you have a program that will remove all of the TurboTax 2016 program segments?
