I have recently purchased No Man's Sky (PS4 Version) I inserted it into my PS5 and installed the PS5 upgrade straight away without installing PS4 version. However i want to us my VR to play but only works on PS4 version of game. I only have the PS5 version installed and i can't figure out how to install the PS4 version. Its easy to upgrade from PS4 to PS5, but can't seem the install PS4 version. Will i need to delete game then install PS4 version first? I appreciate any help. Thanks.
