Windows 10: Remove an application that is already uninstalled from the Apps & features page?

I installed the Riot Client to play League of Legends, then uninstalled it. Now the client is not on my computer but the app on the Apps & features page is still there, and gives me an error when I try and install it. How can I remove this application?

After Uninstalling, App Remains on Apps & features list

Hello,

I removed application from the Apps & Features by selecting Uninstall and following the prompts. After it was uninstalled, and after numerous restarts, the application remains listed in the Apps & features list. Modify is greyed out and when Uninstall is
selected, an error appears, "Windows cannot find C:\[Application Path] Uninstall.exe. Make sure you typed the name correctly and then try again.

First, for Microsoft, the error makes no sense seeing how one doesn't type in the name when clicking the uninstall button.

Second, the reason it cannot find the file is because it was removed when I removed the application the first time.

Now, does anyone know how to get Windows to remove it from the list?

Thanks for the help,

 

Apps and Features list an uninstalled App.

W10-64 Pro. Here is a picture of the problem. Phoenix OS is (as far as I know) UNinstalled.





Using a super file finder, there are no files with the word phoenix in its name on the computer FWIW.

A search of the registry finds a key Phoenix OS in two places. The first is here:

Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall\PhoenixOS





and the 2nd reference is here:

Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall\PhoenixOS

I am assuming removing these from the Registry will clean up the Apps and Features List of Phoenix OS(?)

Any and all advice is appreciated in advance.

Edit: The second registry reference is at:

Computer\HKEY_USERS\S-1-5-21-1742390423-1095737228-4217987103-1001\Software\Microsoft\Windows\CurrentVersion\Uninstall\PhoenixOS
