Hello,
You would need to prepare a macOS installation disk. You would then fully erase your Macintosh’s internal storage device. After macOS is installed you will not be able to restore from a backup (as the backup was conducted on a newer version of macOS).
Alternatively you may ask the application’s publisher if they have a 64-bit version of their application.
