How do i get ride of registry key

I love the program and have been playing with it for a bit. I’m not ready to test my program that puts the registry key in the folder instead of the computer registry but i originally put the key in the computer registry so now when i load the program it looks at the old registry key and doesnt ask for a B key. How do i take the old key out of the computer registry safely? I know how to use regedit but not sure where the key is placed to erase it.

You can clear these registry keys on your computer with the dedicated button “Clear Activation Data”:

What hat about for a computer that I dont have xls padlock on?

That’s not possible, or you can try to change the Application GUID. As an alternative, for testing, you can enable the portable mode in “Additional Settings”.
