This is one of the common problems which I used to face in college times. Some of the software used to have the entry in Add still and Remove section of Windows even if I have used the uninstaller to remove the application or program. Here is a quick solution to remove them from the Add and Remove Section.
Add Remove Program panel is also called Program and Features available in the classic Control Panel.
Fix: Add Remove Program still shows entry after uninstall
The steps below will remove invalid entries in the Add/Remove Programs Tool. Only an administrator will be able to use these steps to fix the problem.
Open Registry Editor by typing Regedit in the Run prompt followed by the Enter Key. Locate the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Locate the key to be deleted by locating the key name created by the program. If the name of the key is not apparent, browse through each key and note the value for DisplayName. This is the viewable string in the Add/Remove Programs tool.
It would be a good idea to take a backup of whatever you are planning to delete. Using the Registry menu, export the selected registry key to make a backup. Store the .reg file in a safe location in case you need to import it at a later date.
Delete the selected registry key and its values. Do not delete the entire Uninstall key. Quit Registry Editor.
Verify that the reference in the Add/Remove Programs tool is no longer visible.
Done that, it would be a better option to use third-party apps to remove such apps. However, always create a System Restore point before doing anything.
That said, if its an important program, and you need to uninstall often or reinstall, it would be a good idea to connect with the developer to pass on the feedback. This process does not remove files left by the program, but only its entry. You will have to delete those files from the Programs Folder manually.
