can i use toast 11 in a mac operating system Monterey

Toast 19 is out and it is compatible with macOS Mojave thru Monterey. Your Toast 11 is ancient and incompatible with current 64-bit operating systems. Due to the age of your toast version, I would be surprised if Roxio gave you any discount on Toast 19.
