Restoring Backup / Legacy Version

Hi!
I have a backup file stored via Cloudberry Backup (v3.4.0.92) on Google.
The computer that the backup was originally taken from is now dead unfortunately.

How can I go about restoring the backup on another computer? I have access to Google and also the backup encryption password but this is obviously an old version of Cloudberry Backup :confused:

Any help would be appreciated!

Update - I think I have the old version of the CB software so I can install that on another computer
