I don’t have a list of these 10-digit error codes, so I don’t know what that code means. The regular macOS error code numbers that I know of, are 16-bit signed integer (-32,768 to 32,767), so I’m thinking your result code might be from a different list, and application specific. I’m just a fellow user, so perhaps someone at Support may know more or be of help? I doubt the script readers recognize the code, but a higher echelon might be able to look it up.
I would delete any of the Preference files (*), even delete the Toast folder in /Applications, reboot with a minimum of peripherals, and try the installer again.
(*) Delete these, if they are present, for a clean slate start: ~/Library/Preferences/Roxio Toast Prefs ~/Library/Preferences/com.roxio.Toast.plist /Library/Preferences/com.roxio.Toast.plist ( ← older Toast versions) /Library/Application Support/Roxio/ ~/Library/Application Support/Roxio/ ( ← not sure which versions of Toast used this folder) ~/Library/Services/ToastIt.service ~/Library/Saved Application State/com.roxio.Toast.savedState/ ~/Library/Preferences/com.roxio.videoplayer.plist ~/Library/Preferences/com.roxio.Toast.LSSharedFileList.plist [where ~ is a shorthand for your home folder, and a / at the beginning signifies the root of the boot volume.]
