How to install new Vfx 1.3.1

Hi Guys, I would like to know how to install the lastest version of Vfx. I mean, I installed the 1.3.0 and then I installed the 1.3.1 release candidate, because it had the mapping for the denon mc6000.
So, Do I have to uninstall the two previous versions, the last one or none. Thanks in advance.
