Minecraft Forums

ok so if i use that i will be able to connect to servers?

Yeah, I read about that on the MultiMC forum. It really does seem like the way to go. It is just a shame that I can't use the client if I wanted to. I also tried to use Tekkit, but that didn't work either. It said something along the lines of "Unable to Authenticate."

But know, MultiMC will not hurt your computer. And it really is simple to use I was able to log in using that. Although, I am not sure if I can play multiplayer yet. I will find out.

I just found that video on how to use it, reddevil. This should help you too, if you decide to give it a try.

ok thanks is that to install mods? cause im trying to figure out how to launch mc from it still

i used multimc but the same error 87 comes up?
