I'm not sure how you normally find C:\ProgramFiles (x86) in Win 10 but if you go Start and type that, it should pop up in the Start Menu.
Click on that then click on each item in the path petsie has listed, clicking on Open after each one.
When you get to the \registry_backup_tool and open that, scroll down to that .ocx file - right click on it and select Copy.
Use your back arrows to go back to where you first see Windows Repair (All in one) - right click on it and select paste.
