While some servers use hamachi to connect the players in virtual LANS, the majority doesn't. So no, you do not need hamachi to play the bought version of minecraft. There are several websites with huge lists of servers you can join without hamachi.
JRE7 is recommended.
yes
You need Hamachi first, then you have to join there Network they should have created through Hamachi. Once you have done that you need to get there personal Hamachi IP and type it in on Minecraft, it should not require a port.
Download the latest version from internet.
you CAN play on cracked servers on cracked minecraft i got a free launcher for alpha and i got an accuont and i dont need to ues a password just my uesr name and enter a server ip and some servers ues hamachi..... by the way it auto updates :D
I think it's because your friend has to make a hamachi network, and you need to join it.
All you need to do is make an account on minecraft then buy the full version. If you do download it and you don't get the latest version you just use your minecraft password to update. If you don't know the password then you need to make a new account. If you've already bought minecraft and you forgot your password then you can redeem you minecraft gift code to buy minecraft for free. But you can only do this when you've bought minecraft before.
A hamachi server is just a normal server. But to play on it, you must download hamachi. Basically, it is a very very easy way to make servers. It is how I make mine. Many server tutorials tell you to use hamachi because it is easier. If you need it, ask me for more details.
You need to have hamachi.
No, you do not. You can host a Minecraft server as long as you have connection. Please note that you need to open your ports on your router to make a Minecraft server. If you do not have access to this, you can download a VPN-software like Hamachi or Cisco.
you need the pc version on the computer
You need minecraft 1.0.0 or over or you can get the minecraft 1.9 pre-release 5.
