I just purchased and installed Snagit 2020 in a custom folder. my old Version 2019 was not uninstalled. When I go to Windows 8.2 Program Uninstall in control panel. Ver 2019 has disappeared from list of installed programs, but all of the 2019 program files are still on computer. How do I uninstall Ver 2019. I do not want the hassle to find, download & install another 3rd party uninstaller program.
