Move current software to new computer

You don't need to "transfer" the software, just install it normally on the new computer same as you did on the old (eg, click Download / Software then Download for Windows on this site).

You'll also want to transfer you scores as well as other your other personal documents, but Windows generally handles that pretty automatically when you set up the new computer and specify the OneDrive address etc. If for whatever reason you choose not to use OneDrive, you could just copy over your Documents folder manually.
