Cannot get my .app files to open in Clarion (9)

Accidentally told the system to always open .app files with Notepad. Now I cannot open any of my projects. I am new to Clarion and I have no idea what to do to fix this. I tried to change the default application to Clarion, but it still won’t allow me to open my projects. PLEASE HELP!!!

Open your app FROM Clarion IDE

This should only be an issue if you double click .app files to open them.

To change the file association, right click on one of your apps and then use the change button to choose the Clarion IDE EXE (C:\Clarion11\bin\Clarion.exe, in my case).
