Francis,

For all applications, you can rent/subscribe to CC and work offline, or you can buy CS6 (or earlier version(s) second hand with a licence transfer through Adobe) and work offline. In both cases, you need registration and actication/verification online, but that will only be now and again.

For CC, you can download here:

For CS6, you can download here:

For further questions, it may be relevant to try the Photoshop forum (application questions),

or this specialized forum (for download/connexion questions),
