So I've managed a server already and I am trying to distribute working copies to my friends, 2 of them received them, both saying it isn't working. But on my PC in another room, I downloaded the same copy I sent, and connected to my server without problems. 1 of the 2 said that they were running Windows7 x64 bit, and I told him to install the 64 bit library installation files, he did and then I sent him another copy and it still didn't work. Not even the laucher showed up. He received an error 339 I believe. for the 2nd of the 2 I'm not sure, he just told me it didn't work.
