Update to 5.4.6?

I’m using 5.0. something and want to update to 5.4.6. I don’t find any ‘update’ links, only the full install download for ver
5.4.6 or the new 6.0.3.

Is there a way to update to 5.4.6 w/o having to uninstall and reintall all over again?

Thanks,

Mac

Operating system, please? That makes all the difference in this case. (Just edit the information into the question.) Thanks.
