installing new unity but affraid the licence will gone

hello… i have unity 4.2 pro and i have bought the licence,
now i want to install unity 4.3.2 but in different folder, because i still want my last unity still there…

i want to ask is, if i install the unity 4.3 will it erase my unity 4.2? and how about the licence? will it lost?
thank you…
i realy don’t understand about the licence…

Hello,

During the install procedure, you can specify which folder Unity should install to. Since any 4.x version uses the same registry locations you license should still work on the newer version, however if for some reason it doesn’t, you can unlink the old version and re-link the new version to your license.

Hope this helps,

PS: I have sever versions of Unity installed
