No, any uninstaller should take care of that.
Let's try something else, before going the REVO uninstaller route......
Go to Windows Control Panel|PROGRAMS AND FEATURES and right-click the Videopad item. Uninstall it. Now reinstall.
If still no satisfaction, try REVO. It runs the Windows uninstaller first. Then it presents further registry 'clean-up' options.
Scan those entries first just to ensure that no non-VP entries are listed, then select ALL and DELETE. There may be several steps before this is completed.
