Netbackup 7.5.0.7 for WIndows 2012 x64

I have downloaded both the x86 & x64 to go from 7.5.0.x to 7.5.0.7.

I don't know what to download to be able to update our WIndows 2012 x64 servers. I know that when I have to install Netbackup on our WIndows 2012 server, I had to download a specific file for this.
